They're both up!

The Google Docs experience is nowhere near as good as DriveThru. Not having previews because the file was too big, for me, is a big no-no.
A net-chum pointed out that it's "easy" for him to get stuff from DriveThru because he's bought so much small press stuff from there that he's just used to it. Sure, it's not actually easy but the perception is that it's easy because he uses it so often. I thought that was interesting from a UX perspective - the UI is a bit fiddly but you get so used to it that the UI disappears and you just see the price and the buttons standing out.
