I'm sure somebody has asked this already but I did a search and can't find the answer I'm looking for. I'm new to the Apple world and I am going to buy an iPad and was thinking of buying a refurbed unit. If I go the refurbed route should I buy a 4th gen or an Air and why/why not? Sadly, I don't really know what I'm going to do with the iPad but it looks like it will be some fun finding out what it's capable of doing. I've wanted an iPad since I got my first Apple device, an iPhone4, about a year and half ago. Having said I don't really know what I going to do with the iPad should the 16gb model be good enough or should I get the higher gig model?
