So I'm finishing up my last year in my undergrad years, and my 3 year old HP notebook is still running fine. However, my mom is running an old machine at home (a 6+ year old pentium 4 computer running windows xp) and I was thinking of passing down my notebook to her. In the meantime, I would still have a computer here (a custom built core i7 desktop I built last summer). I'm thinking of a mobile alternative and the iPad 3 sounds pretty neat to have. For college students, how productive is it for you? How about for those with computers already, do you feel it is a nice extra asset to have? I don't think I could rely solely on an iPad for day-to-day use, but considering I could take it to the library, what do you think?
