I'm looking to get an iPad 2 and I'm trying to figure out whether 16GB of storage space is enough for me. Basically for me, I intend to mostly use the tablet for browsing the web, pictures, e-mails, watching the occasional movies, and reading digital magazines. I intend to store no more than 4-5 movies encoded at 960x540 resolution. It'll mostly store magazines (no idea how big magazines are). Will 16GB be more than enough for me?
