Lenovo ThinkPad X1 Carbon Touch The Lenovo ThinkPad X1 Carbon Touch is a wonderful piece of design and engineering that offers a fearsome performance in a sleek and classy chassis.Lenovo got a lot of things right with the ThinkPad X1 Carbon, and all the advantages carry over to the Carbon Touch: it's light, gorgeous, functional, and powerful enough for every realistic ultrabook task.Lenovo takes its solid 14-inch ThinkPad X1 Carbon and upgrades it with Windows 8 and a touch screen, while keeping the excellent keyboard.The X1 Carbon Touch's built-in 45Wh battery lasted just five hours in our rundown test, which involves looping a movie off the local disk with WiFi on and the brightness fixed at 65 percent. Granted, touchscreen Windows 8 laptops generally don't fare well in this regard (the best lasted 5:32) but even then, a five-hour runtime is slightly troubling.
But, The touch screen makes the lid thicker, and the touch pad can be finicky at times.
The bottom line: The business-oriented Lenovo ThinkPad X1 adds must-have features for 2013, and remains a very impressive business-oriented ultrabook with strong crossover appeal. Specifications

Graphics ProcessorIntel HD 4000 Price:$1,499 VS Samsung Series 9 NP900X3C (13-inch, 2012) This 13.3-inch Ultrabook is all business with its gorgeous anti-glare PLS display, 256GB SSD, Intel Core i5 processor and backlit keyboard. The Samsung Series 9 is one of the most well-rounded Ultrabooks we've seen with excellent performance, decent speakers and a great display. A thin, stylish design, long battery life, excellent screen, and a new second-generation Intel Core i5 CPU make the Samsung Series 9 NP900X3A one of the best ultrathin Windows laptops we've ever seen.
But, While we got used to the trackpad, we still found it to be a hindrance rather than an enabler. The input features - namely the trackpad and keyboard - can't touch the MacBook Air for quality, and that's a big issue. The Series 9's way-too-high sticker price makes the MacBook Air look downright affordable by comparison; the flexy case design doesn't feel as good as the MacBook Air's, either.
The bottom line: There are performance issues, arising from its waif-like size, but it's still more than capable of serving most people's needs, while offering head-turning style that few competitors can offer. The $1,649 Samsung Series 9 NP900X3A certainly won't be for every wallet, but this light, well-featured, and striking 13-incher is the closest the Windows world will ever come to a MacBook Air. However, its higher-than-the-Air price will be hard to stomach.

Optical DriveNone Price;$1,699 / $1,649 VS Apple MacBook Air The MacBook Air has been known for its good battery life.New Intel fourth-gen CPUs help the updated MacBook Air achieve amazing battery life. The multitouch trackpad is still the industry's best, and even better, the 13-inch MacBook Air now starts at $100 less than the previous model.
The new Haswell processors use very little power, giving the 2013 13-inch MacBook Air and absolutely stunning battery life. In our test, in which we streamed the live BBC News channel feed on iPlayer over a wireless network, the laptop lasted for nine hours. That's significantly better than the 11-inch MacBook Air's 7 hours 15 minutes, and a substantial improvement over the 2012 MacBook Air's 5.5 hours.
Since switching to solid state storage off the shelf with the late 2010 update, the MacBook Air has been known for its good battery life. But with the Haswell processors in place, it's absolutely stunning. At last, you can use your notebook all day long on a single charge.
But, Newer features such as touch screens and higher-resolution displays are still missing. The ultrabook competition is catching up, in terms of design.
The bottom line: Apple keeps the latest MacBook Air updates on the inside, but greatly improved battery life and a lower starting price make up for a lack of flashy design changes. Specifications
