I am considering purchasing the 16gig size as I think that will be big enough and I don't think I have the need for 3G. I don't plan on having music on the iPad, and at most 4 or 5 movies at a time. I have a trip coming up soon (across country) and it would be nice to load up the iPad with a few movies, some TV shows and maybe a book or two. I will probably end up with several apps, but not many compared to some peoples standards....not a big game player. Just wondering how many of you have the 16gig model and getting by nicely with the space, or wishing you had a larger model..?
