I'm way behind the game when it comes to Apple products and tablets especially. I'm thinking about picking up an ipad. I'm going to buy a used one because I'd rather spend the money on oakleys. Can someone please give me a heads up on what to look for/avoid? I'm thinking I want a 2nd gen, wifi. I don't plan on or want to add it to my verizon plan unless it's preferred. Again, that's the type of info I need. Also, should I connect it to my computer before I purchase it to see if it connects or what? Hook it up with the infoz pls.
