How many times have you e-mailed files to yourself or used a thumb drive to transfer them between machines? Microsoft is attempting to change this with Live Mesh, which allows you to sync your devices with Micrsoft's cloud. Currently, up to 5GB of files can be stored in the cloud. Cloud computing purists will not like that Mesh requires a software download. But I believe having offline access to your cloud data is critical. Otherwise, you are at the mercy of the cloud.
