Live Mesh really looks like a great product.
But it really only creates confusion since there are already a bunch of similar MS techs like FolderShare, Folder Sharing in Messenger, SkyDrive, Meeting Space, Remote Desktop, etc.
Same thing as on the communication front with a bunch of mail clients, IM clients etc.
Shame that these aren't integrated into a single offering so even inexperienced users could use it. Also even as a power user I getting fed up with having to install many similar apps for a single company just because neither has the full featureset I need.
From outside it really looks like Microsoft was some sort of sports league and each team inside is competing instead of cooperating.
