I plan to have: -5 GB songs -1 GB pictures max. -Plenty of Apps -Plenty of Books/magazines -4 or so movies at a time max (more likely 1-2...but for long trip maybe more) and a TV show or two. I'd like to think 16 GB is OK, just worried about what I don't know. Will movies be more space on iPad...will magazines become highly enriched in content? Ugh. Worth the $100?
