So far I've loaded 33 apps with 380mb music, and I still have 11.6gb left. I only have a few games on my iPad, I prefer to game on my computer. Most of my music stays on my iPod Touch. I think 16gb is going to be just fine for my needs.
I finally signed up after lurking on this forum for years just to tell you this. I got the 16gb iPad this morning and returned it a few hours later for the 32gb. Only had 5 gb free after all the apps I needed were installed,
