This Acer Aspire S13 isn't the most inspiring thin notebook, but it's a remarkably practical and cost-effective choice.
The Razer Blade Stealth offers better specs for less money than the competition, and includes features others lack, such as a high-res touch screen and full-size USB ports. The design is slick, the price is right, but it's not as slim and portable as other 12-inch laptops.
The 14-inch Blade upgrades to more powerful Nvidia graphics and a matte 1080p display. Plus, it starts $200 cheaper.
The Razer Blade Stealth is a rare mix of slick design, great performance and top-notch value in a laptop -- but the great-looking 4K screen on the top-end model takes a major hit on battery life.
The Toshiba Kirabook is still a worthwhile high-end Windows alternative to a Retina MacBook Pro, but it could use a little of that Apple secret sauce for its touchpad.

Asus was one of the first PC makers to go ultra-thin with its Zenbook line. That latest UX301 version packs in nearly every high-end spec you'd want, but it's priced out of reach for most, and lacks an all-day battery.
The design of Toshiba's high-end Kirabook hasn't changed since last year, but it has aged gracefully. The components get an update and the battery life gets a big boost, making this an all-around excellent, but expensive, ultrabook.
New CPUs and a better-than-HD screen make this 2.8-pound ultrabook a top crossover contender.
A major update to our favorite Windows 8 hybrid, the IdeaPad Yoga 2 Pro is still a better laptop than tablet, but the new version adds a future-proof better-than-HD display at a great price.
If you’re just looking for an all-around excellently made Windows touch ultrabook and don’t mind that it's on the expensive side (and doesn’t convert to a tablet), the improved Samsung Ativ Book 9 Plus is worth the investment.
