Argos sells the Barnes and Noble Nook HD tablet from as little as £132.95 with delivery and 129 Nectar points included. This is a brand new device that comes with 12-months warranty and you can also get the more powerful Nook HD+ (which also comes with a full HD display) for £179 at John Lewis.
The Nook HD comes with a smaller 7in display, one that carries a 1,280 x 800 resolution. It is powered by a dual-core TI OMAP4430 SoC clocked at 1GHz and is equipped with 512MB of RAM, 8GB onboard storage, a microSD card slot, Wi-Fi, up to 10.5 hours battery life, Bluetooth and a number of B&N reading applications.
Potential rivals to this tablet include the Google Nexus 7, the Asus MemoPad or the Acer Iconia B1. The latter is an intriguing option as it is currently being cleared out for £79. The 16GB Nexus 7 on the other hand (an altogether more powerful alternative) can be had from £150.
It's worth noting that the Argos description on eBay also lists a different SoC (a more powerful OMAP4470 clocked at 1.3GHz). Check out our review of the Barnes and Noble Nook HD tablet here.
