I am going to be buying a new iPad this week and I'm leaning towards the 16gig model. For those of you that have the 16gig model, has it been enough space? I will be loading up a few TV shows (not a lot) to watch while I'm doing cardio at the gym. Other than that...I'll be using the web browser and e-mail mostly. I don't anticipate needing lots of space. Might throw a movie or two on there when I travel. Just curious if 16gigs has been sufficient for those of you that bought that model. Thanks!
