Is yours 16GB?
No, I have a 32GB. But I have a long commute and load a number of episodes of tv shows and movies onto my iPad, along with some music and previously mentioned work related files. And then of course, there are apps. Also, I tend NOT to shuffle stuff off my iPad back onto my desktop, but keep drafts and final versions of projects on my iPad.
In my ideal world, the next version of the iPad will have Thunderbolt and USB 3.0 capability. I don't like having to spend a lot of time syncing (except to update the OS). Dropbox comes in handy here as well.
