Yesterday, I installed Windows Live Mesh and set up a shared folder. Last night, I installed Live Mesh on my home computer.
Immediately after installation, a folder link appeared on my desktop. The link is to the shared folder from my work laptop. However, files were not downloaded until I clicked the link and told Live Mesh how that folder should be synchronized on that computer. After that, I had free access to those files.
Today, I connected to my home PC from my work laptop (at work). It's nice because my home PC is Windows XP Home (ie. no Windows Remote Desktop). Using Live Mesh's remote desktop seems to work pretty good. I think that Windows Remote Desktop is more efficient though. I am noticing CPU usage on the local PC even when the remote desktop is minimized.
I don't have a Windows mobile phone (I am a BlackBerry guy), so I won't be able to try using that.
I think this is great technology for the right people. I'm not sure that this is for everyone, except for those who may take work home with them.
