I recently picked up a DropBox invite from Richard Davies (thanks Richard!) and the service is an unbelievably nice experience.  I’ve got it linked to a few of my machines and it makes file sync very, very easy.

If you are unaware of what DropBox is, I’d suggest having a quick look at their overview video.  I have found it to be an excellent service and highly recommend it!

If anyone wants an invite- I have a few left so just leave a comment below!
