You can bag a refurbished Sony Tablet P with 3G for as little as £179 direct from Sony with one year warranty and free delivery.
The device comes with 3G and is possibly the cheapest connected tablet on the market. It is powered by a dual-core Nvidia Tegra 2 system-on-chip clocked at 1GHz, has two 5.5in screens with a resolution of 1,024 x 400 pixels each, 4GB of onboard storage (with a microSD card slot), Wi-Fi, 1GB of RAM, and a unique clamshell design.
It has a 5-megapixel rear camera and a 2-megapixel front facing camera as well plus Android 3.2 Honeycomb OS.
The tablet can also be connected to the Sony Entertainment Network and to Sony’s Music and Video unlimited services.
Unfortunately, it's being edged out by cheaper and better tablets like the Samsung Galaxy Tab 2 7.0 and the Google Nexus 7, both of which can be had for just over £150.
