10. Gigabyte X11
Thanks to a carbon fibre shell and 11.6-inch screen, the Gigabyte X11 manages to take the sought-after crown of being the lightest Ultrabook ever – just 975g! It's pretty thin as well, measuring 17mm at its thickest point. But things haven't been skimped on much to get it this light: you'll find an Ivy Bridge Intel Core processor, two USB 3.0 ports and a 128GB SSD. It won't among the cheaper Ultrabooks, but it's definitely one of the most notable.

11. Toshiba Satellite Z930
The Toshiba Satellite Z930-10X manages to offer an excellent balance between power and affordability. It's a very accomplished Ultrabook – thin, light and powerful enough to handle a wide range of tasks simultaneously. The star of the show is undoubtedly the Ivy Bridge processor, which helps to keep the performance in line with other Ultrabooks available on the market, but the wide range of ports it offers are boon as well.

12. Lenovo ThinkPad X1 Carbon
The Lenovo ThinkPad X1 Carbon is an attempt to match the lightness and portability of Ultrabooks (which are obviously desirable to road warriors) with the business features expected of corporate laptops. It's doesn't entirely succeed (there's a lack of connectivity, for example), but it comes close enough to be hard to resist. There's a brilliant keyboard, huge battery life (and rapid charging), a large and fast SSD drive and excellent performance. It's not cheap, but you get what you pay for.

13. Toshiba Z930
Toshiba's flagship Ultrabook range is one of the latest recipients of the new Intel Ivy Bridge processors. The result is the Toshiba Satellite Z930-10X. Although the computer keeps the same chassis as the original Toshiba Z830, the internal components have been given a serious shot in the arm. But is the boost enough to keep Toshiba competitive in the evolving and expanding Ultrabook market?

14. Asus Zenbook UX32A
The original Asus Zenbook is an Ultrabook that still takes some beating, so we always knew its successor would be a great offering. The design and usability are great, from the slickness of Windows 7 with the Ivy Bridge processor to the great keyboard with the subtle backlight. Like its predecessor, the Asus Zenbook UX32A is also slim and light enough to carry around all day and the range of connections, especially the three USB 3.0 ports, is excellent.

15. Lenovo IdeaPad U410
The Lenovo IdeaPad U410's trick is really bring out a value proposition, offering offering a high-end hardware configuration in a mid-level assembly – it's an Ultrabook for the masses. The fact that the Lenovo IdeaPad U410 offers both a third-generation Intel core CPU and a dedicated GPU from Nvidia, along with a healthy amount of storage, makes this one of the most-efficient Ultrabooks that we've come across yet. The build quality may be pretty average, but this is all about bang for your buck, and it delivers.

16. Dell XPS Duo 12
We're going to count the XPS Duo 12 as an Ultrabook, even it is a slightly odd one. Sure, it opens like a laptop, then the touch-enabled screen flips round and you can use it as a tablet. The design isn't new – Dell's used something similar before – but getting it with light and powerful Ultrabook innards is, as is the touch-friendly Windows 8. The screen is protect by Gorilla Glass, and it's a 1080p display, so it'll look brilliantly crisp. All this will come at a price, predicatably, but it'll be a great way to make full use of Windows 8.

17. Sony Vaio S Series 13P
The Vaio S Series 13P is one of the most expensive Ultrabooks we've seen yet, but if you've got the money, it could well prove to be worth it. Both the portability and usability are excellent – so much so, that the excellent specification could almost be forgotten, but you'd be letting yourself down. A Blu-ray drive, a Thunderbolt connection, a backlit keyboard, an SSD and good battery life… the only thing lacking is a 1080p screen.
