The title's quite self explanatory. I have an iPhone 3G and am perfectly happy with everything other than the lag which has crept into it with each successive firmware update after 2.2. I use it for email and occasional 'term lookup' and check fb once a day or so, don't game, use a very limited number of applications. Its more of a phone than an iPhone to me, most of the time. 4G is around the corner and if the pics leaked are something to believe, I'd absolutely want that. Thing is, would an iPad be useful for a med student? I have a macbook unibody and it serves my purpose of movies, med apps, internet and music/movies. Which, in your opinion, should I go for? It'll be a 16 gig 3G iPad vs. lowest capacity next gen iPhone.
