Me too. Dropbox is fast and simple, it's my "sneakernet" at home. I commonly copy files between a Mac and a PC for some projects I work on. Letting Dropbox handle the sync is the most simplistic way to go about it. Most of the files are 1GB or less, so it really doesn't take much time for them to sync, and I have the added bonus of backup and easy off-site access.

My dayjob uses Box, and it works OK, but has just never seemed unique enough to switch over too.

I think I have the $100/year or whatever it is Dropbox plan, I honestly don't even know. I don't seem to run out of space, and it doesn't cost very much so I just don't think about it at all. That, to me, is the hallmark of a valuable service.
