Low cost android tablets are crap. I was looking into them for something to give the kids a while back and once you dig into the weeds, theyre crap. No if's or buts.
I can recommend the Dell Mini 8 or 10 web books.. basically mini lappys with no CD drive. I run a Dell Laptop but the daughters have the 8 and the 10. number refers to screen size. They run fine and manage facebook and facebook games fine, run youtube vids fine and come wireless capable. I picked one up on contract with yodafone and the other bought secondhand for 60 quid from a Cash convertors shop
