Dropbox is way, way more compelling than iDisk, the equivalent bit of MobileMe. Why? Because it just works: your files are always available on whichever computer you're on, so long as it has been recently connected to the net. With iDisk, that's almost never true, and you have to either put up with a WebDAV implementation that's slower than making your own floppies and posting them or a weird hybrid local sync that always breaks. It Never Works, basically, and even if it did wouldn't have the great social and versions features of DropBox. As for the rest of MobileMe, the sync is OK, except when it gets confused. The whole setup is definitely a weakness, it's just one to be exploited in pieces, as DropBox has.
