9. HP SpectreXT TouchSmart

HP Spectre TouchSmart
As befits the Spectre line, the SpectreXT TouchSmart is packing some notable technology. As you may have guessed, it offers a multi-touch display, which will be good for making full use of Windows 8, but is very much an Ultrabook, boasting the latest Intel processors inside. In fact, it'll be HP's first lapop to offer Intel's ludicrously fast Thunderbolt connection. Impressively, HP is also packing in Adobe Photoshop Elements and Premiere Elements, so it'll be a nice multimedia machine out of the box.

10. Gigabyte X11

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

Toshiba ultrabook
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. Asus Zenbook UX32A

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.

13. Lenovo IdeaPad U410

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.

14. Dell XPS Duo 12

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.

15. Acer Aspire S5

acer aspire s5
Thin (15mm) and light (1.35kg), the new Acer Aspire S5 isn't much of a design departure from the older Acer Aspire S3, but it takes advantage of its Ultrabook DNA with a 13.3-inch display, Thunderbolt technology, SSD storage and a fast Intel CPU. If you're looking for a primary laptop that can handle the rigours of everyday life, but be as light and svelte as humanly possible, you've found your ideal laptop.

16. Novatech nFinity 2367 Plus review

Novatech Nfinity
The Novatech nFinity 2367 Plus is the first Ultrabook we've seen that isn't from an established, global computer company. That isn't to say Novatech is small.
The British firm has been selling both components and customised PCs for a while, and in keeping with tradition, there's plenty of choice with its Ultrabook range, with the option of an Intel Core i3, i5 or i7 processor, and varying quantities of storage and memory.
The Core i3 Novatech nFinity 2367 Plus model that we were sent is priced at just £625, and comes with 4GB of memory, a 128GB SSD and Windows 7.

17. Sony Vaio S Series 13P

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.

18. Toshiba Z830-10N

Novatech Nfinity
Toshiba has gone for the thin and light aspects of Ultrabooks with gusto in the 13.3-inch Z830-10N, but has still made a point of including a range of ports, including VGA, HDMI, three USB ports, Ethernet and a card reader, making it a good choice for business use. And, of course, it's got an SSD for speedy operation along with an Intel Core i3 processor – not at the top end of performance compared to the others here, but it should be fine for work use.
