It must be noted that Dropbox solves a problem that Microsoft has been trying to solve for decades. Ever since the MS DOS LAN Manager, MSFT has been working on a file synchronization and sharing solution (and they are only beginning to tackle the synchronization part). SMB, Microsoft Groove, SharePoint, SkyDrive (aka LiveDrive), LiveMesh, Windows LiveSync (aka Folder Share), SyncToy, and even Briefcase, are different attempts at solving the same problem. Still, my Mac and my Windows 7 PC sitting on the same desk won't talk to each other and Dropbox is the only thing that works.
