I've been looking for a new tab and I only have $150 to spend, so I can't buy the 2013 N7. I've seen the refurb 2012 32 gig N7 on ebay for $150 and was thinking about getting it. Is it worth buying? I plan to game and surf on the N7. I'm also concerned about the new Kitkat upgrade. I've read a lot of posts that state there's a lot of problems with this upgrade. The N7 I'm thinking about getting has the earliest version of Jellybean installed, so do I have to upgrade it, or can I wait? I'm pretty much a noob when it comes to anything tech so any help would be appreciated. Thanks.
