This Acer Aspire S13 isn't the most inspiring thin notebook, but it's a remarkably practical and cost-effective choice.
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.
The HP Spectre XT Touchsmart boasts a slim, metal body, a decent serving of power and a Full HD touch-enabled screen for swiping around Windows 8. It's let down by its high price, but you still get quite a bit for the money.
The Asus S400E packs an Intel Core i7 processor into a burly metal shell and doesn't charge an arm and a leg for it. Its touchscreen makes it easy to navigate around Windows 8 but it's let down by a poor resolution and unimpressive colours.
The Sony Vaio Duo 11 offers a Full HD screen, a slide-away keyboard and some very powerful specs. It's a great way to take advantage of Windows 8's tiled interface, but you'll need to make sure you don't mistreat that sliding mechanism.
The business-oriented Lenovo ThinkPad X1 has a few quirks, but is otherwise a very impressive business-oriented ultrabook with strong crossover potential.
The HP Envy 6 Ultrabook uses the latest Intel Ivy Bridge processor to offer decent power from its slim, sleek shell. Sadly, it's let down by a poor screen.

The media-geared Toshiba Satellite U845W has an extra-wide 21:9 screen and Harman Kardon speakers, but no DVD or Blu-ray player. The screen is a novelty act that offers some benefits, but it's really no better than your standard laptop for most uses.
With a Core i7 CPU, discrete graphics, and a full HD screen, the Asus Zenbook UX23VD is pretty close to being the ultrabook that has it all, but you'll pay for all those features.
Meet the new 14 and 15-inch CT-14 and CT-15, Vizio's first forays into the crowded ultrabook arena. We take a close-up look.
