I'm planning on the 16GB WiFi model as well. It should work out fine for me. I can fit pretty much all of the documents I need for work into 2GB of space (I use a free dropbox.com account to sync my work documents between my iMac and MacBook) and I can cram enough audio into a 2GB iPod Nano to last me for a week long trip without a problem. Do I get repeats? Sure, but hey, I've got actual work to do during the day and I only really listen for maybe an hour or so a day at most. The podcasts I like can cram even more programming into that space (NPR stuff, audio drama, etc.). I figure I'll have room for all that, a couple of movies, some books and plenty of room to spare. In a pinch, dropbox already has an iPhone app. I have no doubt it will work on the iPad until they release an enhanced version.
