Virtual desktop in the cloud? All you media across all your devices?
I'm a big fan of Skydrive - 5 gigs of free space you get and no annoying ads. I put most of the presentations I do up there as well as most of the images I use on this blog. The problem though has been accessing all the stuff I put in there easily from anywhere and also keeping my devices in sync. Enter Mesh.
Check out mesh today - spots are filling up fast so if you don't get in to this round of test accounts, sign up for the waiting list. Mac support coming soon too.
LiveSide.Net has a some a first impression writeup as well as more screenshots of the interface. Check it out here.
Update 4/28/2008 - Check out the interview with Ray Ozzie as he discusses Live Mesh - here on Channel 9!
