I wonder when 'eventually' will be. The rate things are going, we might see Microsoft apps pick up Mesh sometime in 2013. When everybody else has already got a better, more evolved offering.
I'm going to try Mesh for my favorites, though. I've tried it for a lot of things, and constantly found that it didn't work. Syncing the folder with all your RSS feeds doesn't work. Syncing Live Mail's mail store doesn't work. Syncing the Music folder to the Music share on WHS doesn't work. Everybody keeps telling me Mesh is so great, but currently it's just a slightly more cumbersome Synctoy that rarely works for anything that's more than a simple folder with some files, so I'm wondering which amazing feature from the Beta I overlooked.
And yeah, I understand the whole "It's a platform" thing, but that doesn't help me now. Right now, there's no SDK. It doesn't sync any data other than files. There's no amazing cross-device syncing. There's just a small application that allows me to sync files across my Windows PC's... and that doesn't include a Windows server.
