HP's first tablet PC, the HP TouchPad, has been made available to pre-order from The Carphone Warehouse.

Both the 16GB and 32GB versions of the 9.7in tablet, which are priced at £399 and £479 respectively, will be available through the retailer, although the device isn't available with a data plan as it currently doesn't include 3G connectivity. However, HP plans to release a 3G-ready version of the device later this year.

The HP Touchpad, which is powered by a dual-core 1.2GHz Qualcomm Snapdragon processor, runs the latest version of WebOS, which HP acquired when the firm bought Palm last year for $1.2bn.

The Touchpad interface groups applications logically as 'card stacks', when a user is finished with using an app they can simply flick it off the screen rather than shutting it down. Furthermore, touching a compatible WebOS phone to the tablet can automatically fire up a browser on the phone and display the same web page that's displayed on the tablet.

Users will also benefit from a 9.7in touchscreen display with a resolution of 1024x768 on the device which is just 13mm thick. It has a 1.3 megapixel webcam, and allows video calling.

Although the Carphone Warehouse has yet to specify when the TouchPad will be delivered, HP revealed earlier this month, the device should hit shelves in the UK by mid-July.
