Hello, I decided to buy my first iPad on a whim. I'm still not sure I'm going to keep it, but I figured I'd give it a shot for 14 days (I don't know if I can justify the price, given that I have a great MBP and a nice iPhone)... Anyways, the main reason I picked one up is because I am going on a trip in May to Portugal. I figured this would be nice to have to watch movies on the plane ride over. But now I'm thinking having Internet access would be nice too. Im not sure if anybody knows what would be more cost-effective: returning this iPad for an AT&T model and using their international roaming, or buying a 3G or 4g hotspot? Any ideas? Thanks!
