From Wikipedia, the free encyclopedia
Ultrabook was created as a specification and trademarked brand by
for a class of high-end
designed to feature reduced bulk without compromising battery life. They used
processors, , and unibody chassis to help meet these criteria. Due to their limited size, Ultrabooks typically omitted common laptop features such as
ports. Ultrabook is a
In 2012, Intel Capital press officer Jordan Balk Schaer announced a new fund to support startups working on technologies in line with the company's concept for next generation notebooks. The company set aside a $300 million fund to be spent over the next three to four years in areas related to Ultrabooks. Intel announced the Ultrabook concept at
in 2011. The Ultrabook would be a thin (less than 0.8 inches thick) notebook that utilized Intel processors, and would emphasize portability and a longer battery life than other laptops By this marketing initiative and an associated $300 million fund, Intel hoped to influence the slumping PC market against rising competition from
and , which are typically powered by competing -based processors.

The Ultrabook directly competes against other subnotebooks, including ’s , which has similar form specifications and is powered by Intel CPUs, but is not advertised under the Ultrabook brand.
in 2011, four Taiwan
showed prototype Ultrabooks that used Intel's
chips. Intel plans to reduce power consumption of its chips for Ultrabooks, like Ivy Bridge processors, which will feature 17W default thermal design power.
At a presentation at the , an Intel manager stated that market analysis revealed that screen size motivated some of the reluctance to switch to 13" Ultrabooks. As a result, Intel planned to ensure, through cooperation with manufacturers, a 14 or 15-inch screen on 50% of the 75 Ultrabook models that would likely come to market in 2012.
IHS iSuppli had originally forecast that 22 million Ultrabooks would be shipped by the end of 2012, and 61 million would be shipped in 2013. By October 2012, IHS had revised its projections down significantly, to 10 million units sold in 2012 and 44 million for 2013. The cheapest Ultrabooks started at $900 USD, instead of the more mainstream $600 USD (as of 2012), and most Ultrabooks retailed at well over $1000, making them too expensive for wide adoption. In addition Intel's constant changing of Ultrabook specifications caused confu and this was compounded by OEMs that released slim/"sleek" or "Sleekbook" laptops (e.g.
Pavilion TouchSmart 15z-b000 Sleekbook, Samsung Ativ Book 9 Lite) that are cheaper AMD-powered variants of their more expensive Intel-equipped Ultrabooks. Overall there was the shift in the market away from PCs as a whole (including Ultrabooks) and towards smartphones and tablet computers (particularly the ) as the personal computing devices of choice.
Intel banked on the release of
as well as new form factors, such as "convertible" laptops with touchscreens and tablets with keyboard docks, and features (accelerometers and gyroscopes for touchscreens, hand-gesture recognition) to build demand for Ultrabooks. With the third generation Ultrabook specification, introduced in June 2013 alongside its new
processor architecture, Intel also added the requirement for all future Ultrabooks to
the requirement is intended to prevent "game-playing" and market confusion from OEMs, who had offered low-end products with touchscreens but not Ultrabooks.
Intel required that manufacturers meet certain specifications to market a laptop as an Ultrabook. These requirements changed with each release of Intel's .

Acer Aspire S7-392-6411
It's hard to believe, but we're getting close to the one-year mark in the Windows 8 era. Microsoft's still-controversial operating system was released in October 2012, and that was long-enough ago that we're now seeing the second generation of some of the initial-launch-period Windows 8 laptops and hybrids.One of my favorite early
laptops was the Acer Aspire S7, and it quickly became a favorite for much of the rest of our PC-savvy staff as well. The
scored points by being a new-from-the-ground-up ultrabook, rather than an existing
product updated with new software. The new version, the S7-392-6411, essentially identical on the outside, remains one of the thinnest, slickest-looking ultrabooks available, highlighted by a white minimalist chassis and a lid covered with Gorilla Glass.Since then, we've seen many thin, touch-screen
with high-end processors and 1080p screen resolutions, including the
and the , plus impressive hybrids such as the . Despite the increase in competition, this remains a great, eye-catching design, thanks to the bold white-and-silver design (a nice break from the dark palette of most laptops) and the Gorilla Glass lid, which promises strength and a lighter overall weight.

The new Aspire S7 moves to Intel's latest fourth-generation Core i-series processors. The 2012 version we tested had a previous-gen Core i7 chip for $1,649, while the 2013 model has a Haswell-generation Core i5 for $1,399.99, which includes a 128GB solid-state drive (SSD) and 8GB of RAM. That's a premium price, especially for a Core i5 laptop, considering a
starts at $1,099, but it's competitive with similar Sony and Samsung ultrabooks. This is a hard laptop not to like, and even though the basic design is about 10 months old, it still feels very cutting-edge, at least visually. The $1,399.99 price is still a bit of a reach, especially considering that I don't love the keyboard and touch pad, but it's also very portable and reasonably powerful, and will look great at a coffee shop.

Design and features Aside from moving a few ports around and the absence of the words "Professionally tuned" stamped above the keyboard, this is essentially the same Aspire S7 design we liked so much last year. It's very thin and light, although the glass-covered lid feels a bit top-heavy. You may recall that the original
(from early 2012) had a similar design, putting glass both on the back of the lid and the wrist rest. Here it's just the lid, which is good, as it never really worked on the wrist rest.

Of course, this isn't an all-glass laptop (which sounds like a crazy idea, but I bet someone will eventually pitch one). The rest of the body is aluminum over a plastic base, and the entire thing has a MacBook-like feel. White (behind the glass surface on the back of the lid) and silver is an unusual, but not unheard-of, color combination these days. Most laptops, apart from MacBooks, tend to be matte or glassy black, with maybe a little gray or some red accents thrown in. Just by being different the Aspire S7 achieves an upscale look that stands out.The keyboard has flat-topped, island-style keys that sit in a gently sloping, indented keyboard tray. The keys feel deeper than the original S7's, based on my memory of that system, making for a less error-prone experience -- but it may just be that my tolerance for shallow ultrabook keyboards has grown with repeat exposure. One thing I miss is having a separate row of F instead those functions are mapped as alternates to the numeral keys. It's an odd omission, as there's plenty of room at the top of the keyboard for an additional row.
Sarah Tew/CNET
The large touch pad has a great surface with just enough friction, but multitouch gestures are a bit finicky. Interestingly, this version has a Synaptics touch pad, rather than the Elan model on the original S7 from 2012. Side by side, I'd say this new S7's touch pad is more responsive, but it still pales in comparison with what you get from a MacBook.One highlight of the system is the 1,920x1,080-pixel-resolution, 13.3-inch display. Despite some touch-screen laptops making their lids slightly thicker, the lid here still seems very thin, and is perfectly flat, not convex at all. The screen has decent off-axis viewing and while it's glossy, it's not overly reflective.The screen hinge is designed with touch-screen use in mind. It acts like any other laptop hinge from the closed position to about 120 degrees or so. After that, the hinge stiffens considerably, so tapping and swiping on the screen results in less shaking or movement under your fingers. It's a small feature, but a clever one for Windows 8 laptops.

Connections, performance, and battery On a small laptop, you're going to give up a certain number of ports and connections, but at least the new S7 has two video outputs, HDMI and Mini DisplayPort. You also get a couple of USB 3.0 ports and an SD card slot, but no Ethernet jack, which would be tough to fit into the slim body.
