The new line-up of computers from Lenovo includes a super-slim all-in-one desktop PC, another that works as a television, and a 12.5in widescreen laptop.

The Ideacentre A320, a desktop ‘all-in-one' computer that combines the screen and processing components into a single unit, is just 18.5mm deep at its thinnest. It has a 21.5in widescreen display, an Intel Core i5 processor and HDMI inputs and outputs.

A TV tuner is available as an optional extra. It also uses Lenovo's Directshare technology to allow files on the computer to be easily shared over the internet. The A320 will be available from £599 depending on the configuration.

The B320 model is a 21.5in all-in-one that is also a television set - without having to start the computer, users can quickly watch high-definition (HD) television channels. It has a Core i5 processor and prices will start at £650.

While both the A320 and B320 have touch-sensitive screens, a third model, the B530, has a more advanced and more accurate touch-screen, a Core i7 processor and a 23in display that can show high-definition video in the highest 1080p resolution. It will cost from £799 when it arrives in June.

Lenovo was showing off its forthcoming products at the Gadget Show Live 2011 at the NEC in Birmingham. You can read more of our Gadget Show reporting by clicking here to read our Gadget Show Live 2011 news blog.

Datawind is hoping to attract the interest of consumers unfamiliar with its Ubisurfer brand with a seven-inch tablet PC under the £100 mark that includes free internet access for a year.

Launched at The Gadget Show Live 2011, the Ubisurfer Touch 7 runs Android 2.2 and has a multi-touch screen. Notably, Datawind has been careful not to use the term 'mobile broadband' in relation to the free web access, as the device supports only the GPRS data network. This network is limited to 14.4Kbits/sec, which is about the same you would have got from a dial-up modem from years gone by.

Datawind insists that compression software supplied with the tablet will give users a "3G-like experience", but with even the slowest mobile broadband services hitting an average of 1.73Mbits/sec, and figures in the range of 2 to 3Mbits/sec for the UK as a whole, this seems a bold claim.
