I have been using Dropbox as a Mobileme’s iDisk Substitute for cloud storage mainly because I use the Mac GTD app Things. The purpose of Dropbox in this context is so I can sync across several Macs by pointing Things at the Dropbox folder on each Mac. The suggestion came from the Cultured Code Things forum that I give Dropbox a try, and it works like a charm. Without any question this is the best iDisk alternative. You can check it out at http://www.getdropbox.com if you like. And Dropbox has created a snappy iPhone web interface to boot. Unfortunately it is an invite only beta at this point, so….
I have 9 Dropbox invites to give away. First come first serve.
