Jack - This was mentioned in a thread Tech: Android Tablets 2012 - What's Useful? about useful stuff for an Android Tablet. It might be worth a look.
I recently bought a 7" Android Tablet (around £75 for the tablet plus another £11 or so for a carry case which includes a keyboard for typing using small real keys) and 10" ones start around £110 on ebay.
Quack!
