Use your GMail account as Harddrive

GMail Drive shell extension (viksoe.dk)

I think my weblog is becoming like a Googleblog. Don't blame me...... Google has so much craze that so many people are developing something for Google all the time. The latest is GMail Drive - it simply adds a new drive to your computer (like C drive), where you can just copy or drap'n'drop files into it.
I think this is really cool. If you don't have storage in your computer, just create new GMail accounts (ofcourse, from invites) and store files into it. I'm not sure how large individual files can be. Also, I don't think I'm gonna use it as IE is required for it - I switched to Firefox.
