HP has updated its TouchSmart range with new touch screen laptop and desktop models, all featuring Windows 7 and a number of applications specifically designed to let owners navigate services such as Hulu, Netflix, Pandora and others using their fingers.

The TouchSmart 300 incorporates a 20-inch display while the TouchSmart 600 features a 23-inch. They'll be available with AMD Athlon II X2 and Intel Core 2 Duo processors respectively, 4GB of RAM and a slot-loading DVD burner. Both offer up optional Blu-ray burners and integrated TV tuners as well as HDMI and composite video inputs on select models allowing users to hook up gaming consoles and other video equipment.

The 20" HP TouchSmart 300 starts at $900 and will begin deliveries on November 1, with the 600 due October 22 and priced starting at $1,050. HP also announced the TouchSmart tx2 notebook, which updates the original convertible tx2, and has a 12.1-inch capacitive touch screen that also accepts stylus input. The updated model uses AMD's Turion X2 processor and will start selling at $800 later this month.
