Not sure if many of you have this already, but it's a cool extension that allows you access to your 1GB gmail account from windows explorer.

I like to take advantage of the 1GB space so I often send myself big files just to use as storage. with this extension, I don't need to open a browser anymore. Just open up windows explorer and it sees it like a portable drive. (of course you need to have internet access for it to work).

GMail file systems have been around for linux systems for awhile now... but I just found this windows version.
