The Barnes & Noble Nook HD and Nook HD+ tablets go on sale in the United Kingdom today, three weeks after the Nook Simple Touch GlowLight made its British debut. Starting at £159 (approx. $254) and £229 (approx. $365) respectively, both devices can be obtained in-store and online from a number of big retailers.

Those include Argos, Asda, Dixons, Sainsbury's, Waitrose, Blackwell's, and Foyles. Alternatively, you can buy the devices direct from Those who have already pre-ordered theirs can expect their package to "arrive throughout the week," Barnes & Noble says.

The Nook HD, the more affordable of the two devices, offers a 7-inch 1440×900 display with 243 pixels-per-inch. It's powered by a 1.3GHz dual-core OMAP 4470 processor, and 8GB or 16GB of internal storage — which is expandable via the microSD card slot. The device weighs just 315 grams, which makes it "20 percent lighter and a centimeter narrower than the Kindle Fire HD," B&N says.

The Nook HD 8GB model is priced at £159 (approx. $254), while the 16GB model is priced at £189 (approx. $302).

The Nook HD+ offers a larger 9-inch display, with 256 pixels-per-inch, making it even sharper than the Nook HD. It also has a slightly faster 1.5GHz dual-core OMAP 4470 processor, but is a little heavier at 515 grams. Still, B&N insists this is the "lightest full HD 9-inch tablet ever invented."

The Nook HD+ 16GB is priced at £229 (approx. $365), while the 32GB model is priced at £269 (approx. $429).

Like the Nook Simple Touch GlowLight, both the Nook HD and Nook HD+ offer British users access to more than 2.5 million digital books via the Nook Store.
