Think this is the cheapest quality tablet yet. Only 8GB out the box but supports micro SD so cheap to make up to 40GB storage with a 32GB card. Also has rear facing camera which was an essential for my mate to do her ebay listings off it.
Available in silver and white at this price. Powerful dual core with a decent GPU means it will do most things (about the same spec as an S2 phone). Jelly Bean is also supposedly imminent and it already has ICS on it.
Cashback is direct from Samsung here: http://www.samsung.com/uk/tab2cashback/
Edit: Price after cashback is £119 not £129. Monday morning is a bad time to do maths, the deal is even better, LOL
Edit 2: Clearly haven't been paying much attention as this is exactly the same as the CPW deal here: http://www.hotukdeals.com/deals/samsung-galaxy-tab-2-7-wi-fi-8gb-white-silver-now-149-00-119-00-after-cashback-carphone-1355621
Lots of us prefer Amazon though so take your pick.
