I gave up on using Google Docs today and replaced them with Dropbox. My brother insisted on trying them out and I did. What can I say, I like it so far. This was the best experience working with remote storage space that I ever had.
They give away 2 gigs for free, and this is more the enough for basic usage — my documents, contracts, some minor paperwork, like registrations, licenses, serials, etc were doing well enough on 256MB drive. 4x times like that would be just great.
One of the minor unhappiness was that shared folders eat up my space (as well as the document owner's). My brother shared with me some of his stuff and I got 20% less off the space. Not a big deal, though.
I try to stay away of advising some services, as far as the most of them tend to become worse within time. But the Dropbox is really cool thing to try.
