The PlayStation 3 firmware v4.10 update brings more than the usual 'stability' changes - it brings something useful - no, not x-game chat.
It brings filesharing with other devices via the loveliness that is DropBox.
If you've not used it, DropBox is basically cloud storage that can be used over a variety of devices for free with 2Gb storage or by subscription with a lot more.
Terminalgamer has "tested everything from music to movies, all downloaded with no problems at all, and boy were the downloads fast!"
Hurrah for progress.
