Lenovo is stealing a march on rival laptop makers by announcing what it will be showcasing at this year's Consumer Electronics Show in Las Vegas. Most announcements are expected to be made tomorrow and Wednesday as press briefings are held ahead of the wider unveiling of this year's hottest tech items.

Lenovo's IdeaPad Y650 will distinguish itself by being the thinnest 16in laptop around. This size of laptop started appearing in mid-2008, prompted by interest in Blu-ray high definition video playback possibilities on high-specification laptops. The proportions of the 16in screen mean it will be able to display high-definition movies with having to contort the footage to fit the screen.

Two more models in the IdeaPad Y series, the 15in Y550 and the 14in Y450, will go onsale in March. The Lenovo IdeaPad Y650 will cost $1,119 - a remarkably similar price to Apple's Macbook Air, which launched at last year's Macworld Expo and also trades on how slim it is.

Dolby Home Theater onboard sound and one-touch access to video and music playback controls will also feature. Lenovo has also equipped the IdeaPad range with limited multi-touch functionality, so you'll be able to use a touch-sensitive portion of the screen to initiate application switching and to zoom in and out of photos using the multi-touch keypad. Full multi-touch capabilities are not included on these models.

Lenovo says the smaller two IdeaPad models, the Y550 and Y450, will have similar specifications to the 16in model and will each cost $850.
