Good enough for private, not sure about business, but it's inevitable
Dropbox is good enough for me. It syncs files between my work PC, home Mac, work iPad, home iPhone, girlfriend's Windows laptop, etc. Does so very efficiently, quickly and without any fuss. In fact I prefer the experience on the iPad way more than using any of Apple's own file syncing features. I can't figure out exactly what iCloud is meant to do either.
A lot of our staff use it for work. I've given it a dubious OK, as long as they don't use their accounts for ANY customer data; make sure their accounts are registered with work email addresses, not home; and make sure the computers they access them comply with our security specifications.
I know Dropbox may be far from perfect but I prefer it to the alternatives:
- USB keys, which have a common habit of walking off
- Emailing documents to their private accounts
- Printing absolutely everything off
- Me being ultra paranoid and banning access to any data outside the network, which will just make it harder for people to do their jobs
