New Apple iMacs expected in May



A recent tweet by Brian Tong of CNet implies a May release date for the new line of iMacs.

He states, "My Sources: New iMacs en route by ocean to U.S. available end of April or 1st week of May. No major cosmetic changes."

If the report is to be believed, the new iMacs are expected to run Intel's latest Sandy Bridge processor and feature the latest Thunderbolt I/O interface ports. Thunderbolt is the new interface technology developed by Intel. It is similar to the USB port but promises to deliver 20 times better performance.

For the past couple of years we have not seen a major redesign of any Mac, be it the iMac or the MacBook Pro and the update would be on similar lines. You may not see any cosmetic changes, except for some feature enhancements.

Earlier in the year Apple updated the MacBook Pro line of laptops with Sandy Bridge Processors, upgraded AMD discrete graphics, Thunderbolt I/O and faster RAM.

The iMac line was last updated in July 2010.

Slickly designed hybrid: Sony Vaio YB Series review

Part netbook and part notebook, Sony's new mini straddles a few fences at the affordable end of the ultra-portable spectrum.

Sony has grabbed AMD’s new portable-friendly APU and gone to town with a design set to win hearts and minds. This light-weight ultra-portable design weighs in somewhere between a netbook and a full-power (read: expensive) notebook.

The Sony Vaio YB Series notebook (of which we looked specifically at the VPCYB16KGG model) uses the AMD Processor E-350 with AMD Radeon HD 6310 Discrete-Class Graphics. The E-350 has a dual-core “Bobcat” design running at 1.6GHz and 1MB of L2 cache combined with the 80 graphics cores of the Radeon 6310 design running at 500MHz. The APU is tied to the system with a Hudson M1 chipset providing system IO.


The Vaio YB integrates an 11.3in LCD with a resolution of 1,366 x 768. We like this resolution at this screen size, the screen is just big enough to accommodate it, so it looks nice and sharp while also meeting the pixel count requirements for 720p HD content. The YB’s display also has an extremely high-gloss finish – and it’s one of those love it or hate it techs. It gives the display an extremely clear and sharp aspect, but woe to you if you’re sitting under a bright light (or the sun) as it’s very reflective. The system also includes a 500GB hard disk drive, 802.11bgn from Atheros and an “Assist” button on the top of the chassis, which loads help software or system recovery software as needed.

On the bench the Sony Vaio YB ran beautifully. It’s a slick machine with a slick design. The E-350 processor is more than comparable performance-wise with an Atom chip, and offers a user experience more along the lines of a Pentium. It was definitely more responsive than Intel CULV processors, but so is a pen and paper.

We got over six hours out of this notebook with a moderate level of usage during the day. The system is more than capable of dealing with internet tasks, basic business tasks like email, word processing and none-too-fancy spreadsheeting, very basic picture editing and resizing and so on.

The downside to this model would have to be the trackpad. We found it too small, too slick and too inconsistent – a surprise in a Sony product, where product interaction is usually half the story. Unfortunately, we kept on pressing the Assist button instead of the power button (which is in the hinge of the unit) out of habit, which would boot up a recovery environment instead of Windows 7 Home Premium. Annoying, but something you’d get used to extremely quickly.

Toshiba Satellite A665-S5176X


The good: A Blu-ray drive and excellent speakers make the Toshiba Satellite A665-S5176X worth considering for those looking for a reasonably priced 15-inch multimedia laptop.

The bad: Uninspiring design, a middle-of-the-pack battery, and a bulky feel keep it from being a standout.

The bottom line: While the $799 Toshiba Satellite A665-S5176X is an affordably priced Blu-ray laptop with a next-gen Intel Core i3 processor, there are other options out there that offer better design or performance for the same money.

The value equation for laptops is changing. Case in point: while the Toshiba Satellite A665-S5176X only costs $799, somehow it just doesn't feel like a great bargain anymore. That's not to say it doesn't have merit: a Core i3-2310M second-generation Intel CPU, 4GB of DDR3 RAM, and a 500GB hard drive, plus a Blu-ray drive and next-generation Intel Wireless Display, make for a decent setup--especially with the included Harman Kardon speakers that can do a movie more justice than most laptop audio rigs--but this laptop is far from perfect.

It's an improvement in terms of battery life and CPU performance over the Satellite A665 models we reviewed last year, such as the Satellite A665-S6058, but the fact remains that other great laptops with second-generation Sandy Bridge processors are available in the same price range, including the recently reviewed 13-inch Toshiba Portege R835 and 2011 Dell XPS 15.

There are other drawbacks: The Satellite A665-S5176X is heavy. Its battery life is unimpressive. And for media playback and gaming, it doesn't have the level of graphics and screen resolution we'd hope for on a large, 15.6-inch-screen laptop. While you're getting a solid package, it just doesn't add up to something that's particularly inspiring.


Toshiba's Satellite laptops feel stuck in a design time warp While the look has been spruced up a little with new raised keyboards and patterned textured plastic (Fusion X2 Finish in Charcoal) meant to reduce fingerprints, the whole package comes off as being, well, kind of garish and tacky. The plastic chassis flexed a lot on the sides when we pressed down with our fingers, and it just doesn't come close to laptops like the MacBook Pro or Dell XPS 15. Yes, in fairness, the actual weight of the A665 is pretty close to that of the 15-inch MacBook Pro, but its bulk is significantly greater. Nevertheless, this is virtually the same design as last year's A665 models, such as the Satellite A665-S6058.

The raised island-style keyboard has comfortably spaced keys and includes a number pad, but the spacebar is oddly small and the keys feel overly slick to the touch. An LED-backlit touch bar above has hot keys for volume, Wi-Fi, and a power management Eco Utility control panel, though the keys make an annoying beep when pressed that takes sifting through buried settings to deactivate. The wide touch pad is covered in a matte plastic and feels responsive, but the large twin plastic buttons beneath the pad contribute to this laptop's budget feel.

Similarly, the 15.6-inch inset glossy display, with its maximum resolution of 1,366x768 pixels, simply doesn't feel top-of-the-line. Viewing angles are limited, colors looked washed-out at times, and Blu-ray playback simply didn't pop like it did on the admittedly more expensive 1080p screen on the Dell XPS 15. DVDs do gain the benefit of upscaling thanks to included Toshiba software, and as a result they look better than average, but for most other media the video quality falls short of excellent.

Snazzy Harman Kardon stereo speakers help the audiovisual experience out, and then some. We've always like the higher-end speakers on Satellite laptops, and the Harman Kardons continue to stand out with crisp, rich audio. And yet, they fall short of the popping, booming excellence we heard on the XPS 15. They're definitely excellent for music, movies, and gaming, but we can now say, unlike last year, that we've heard better.

The Webcam is not the HD type we've been seeing in a number of 2011 laptops: maximum resolution caps at 640x480 pixels, and the built-in camera software offers bare-bones control.



The Satellite A665-S5176X lacks Bluetooth, but has second-gen Intel Wireless Display 1.2 for streaming HD video to a TV equipped with a Netgear Push2TV receiver box (sold separately), as well as a USB 3.0 port. There are literally dozens of Toshiba Satellite A665 co

nfigurations on Toshiba's Web site, each with a different mix of processors, graphics, and media drives. This configuration's 4GB of RAM and 500GB hard drive aren't shabby, but we'd probably trade the Blu-ray drive for more advanced dedicated graphics.
A second-generation 2.1GHz Intel Core i3-2310M CPU powers the S5176X, and its performance is generally better than last year's Core i-series processors. It's a step behind 2011 Core i5 and i7 CPUs in terms of multitasking speed, but this laptop can certainly handle most mainstream and even multimedia tasks put to it. The S5176X handled HD video streaming, multiple-window computing, and even light gaming well, albeit with a stream of very hot air being blasted out the vents on the left edge, just far enough away from where our hands tended to rest while typing.

Thunderbolt MacBook Pro: The last notebook you'll ever need

From the outset, Apple's MacBook Pro has been the standard-bearer for professional notebook computers. Apple's extra-mile engineering sets the bar for performance, durability, build quality, longevity, ergonomics, battery life, and connectivity. For the past several years, Apple has had only itself to outdo with each new generation of MacBook Pro, yet Apple has still managed to set the pace, mostly with upgrades to materials, graphics, disk size, and battery life.

Not to take such advances for granted -- after all, the one-piece machined aluminum frame and dynamic GPU switching were among many unique and jaw-dropping innovations -- but where's the ultimate to-die-for model year leap, the upgrade so substantial that we may not see its like again for five years? As tight as money is now, buyers want to see double, triple, and order-of-magnitude level improvements to justify spending $1,799 to $2,499 on a notebook.

With the new Thunderbolt MacBook Pro, so nicknamed for its revolutionary high-speed I/O port, that's just what you'll get. The 15- and 17-inch quad-core models deliver twice the CPU performance of Core 2 Duo, three times the graphics performance of the previous generation's Nvidia GeForce GT 330M, and more than ten times the external I/O bandwidth of 800MHz FireWire. Even with a base price of just $1,199 and dual-core instead of quad-core CPUs, the new 13-inch MacBook Pro still outpaces prior Mac notebooks in terms of CPU and I/O performance.

This brand of magic can't be conjured by Apple's competitors. Sustained innovations like the MagSafe quick-disconnect charge port, the industrial-grade frame machined from a solid block of aluminum, digital optical audio input and output, automatic integrated/discrete GPU (graphics processing unit) switching, and a five-year battery already have no equal.

Now Apple has integrated Intel's just-released second-generation Core i5 (13-inch MacBook Pro) and Core i7 (15-inch and 17-inch models) into its popular commercial notebooks. By doing so, MacBook Pro has picked up the power of Intel's Turbo Boost dynamic overclocking, Hyper-Threading thread acceleration, 1,333MHz of DDR3 RAM, large Level 3 cache, and integrated memory controller. Intel's speedy new silicon and enlightened bus design, combined with Apple's full-custom motherboard and software, delivers those 2X CPU performance gains bragged about by Apple and proven in my benchmarks.

In the 15- and 17-inch models, Intel's stellar CPU is married with the most powerful and power-efficient mobile GPUs on the planet, AMD's Radeon HD 6000M series. The 17-inch MacBook Pro and the 2.2GHz 15-inch model feature AMD's Radeon HD 6750M GPU with 1GB of GDDR5 RAM, while the base 15-inch model uses the Radeon HD 6490M with 256MB of GDDR5 RAM. Apple uses a clever and simple technique to switch between low-power Intel integrated graphics and the gaming-grade AMD GPU on the fly. This is central to achieving a verified seven-hour battery life across all models, and that's without cheating: wireless networking active, display at midlevel brightness, and even battery-draining Flash Player running in the browser.

If, in all of this, you can't see a reason to upgrade your notebook, maybe I can bring the point home: This might be the last notebook computer you'll ever need or want. After more than two weeks of continuous testing, it's hard for me to imagine what I'd want in a notebook in three to five years that MacBook Pro doesn't deliver right now. Whatever I want, I'll plug into Thunderbolt, the game-changing 10-gigabit peripheral interconnect that deserves (and gets) its own section in this review. I have no lingering doubt that a PC notebook maker might trump MacBook Pro. What Apple has done requires metal, glass, genius, and OS X. It can't be replicated with plastic and Windows.
