I am buying a new tablet (have already posted) and want it mainly for checking email, web surfing, ebook, but not gaming. Because I won't be using it a lot, I don't want to be spending £500 or more, rather £250-£350ish. I am now considering the lenovo ideapad - quad core, and samsungs galaxy tab - dual core - and note - quad core. Is there much of a visible difference if I'm not gaming, in the quad/dual core tablets? I've had varying opinions, so any input will help. thanks.
