"I got a few paragraphs in and thought, "I can't wait to tell him about DropBox!""

I was thinking the same thing. I've been using dropbox for a month now after getting bored fiddling with USB drives and Gmailing .docs to myself to get them onto different machines. Its brilliant.

But there are some new applications of the `cloud. Last month I copied the superb physics game 'World of Goo' (shameless plug) onto a laptop for entertainment on a business trip, but transferring my progress from desktop to laptop meant figuring out where Vista had hidden the save file, transferring it via USB to the desktop, then figuring out exactly where XP wanted it placed.

Now Valve have announced their Steam client will be updated with a save-game cloud feature, something that's never really been present in singleplayer gaming before.
