Dropbox
I must say I’ve fallen in love with Dropbox. I heard about it on Facebook some months ago, but I thought it was just some kind of glorified on-line backup service.
I was wrong, however.
What Dropbox gives you is a folder that is synchronised over the Internet with their servers and from there onto your other computers. This means you don’t have to make a special copy of your files in Dropbox, but instead you can simply keep your important files in your Dropbox folder, and they’re always available everywhere. You just work on your files inside that folder, and any changes you make are quietly synchronised.
Furthermore, you can share folders with other Dropbox users, which gives you a really smooth way of sharing files with coworkers and friends and family.
You get 2GB for free, so do try it out!
The free space is closer to 3 or 4 GB. You get some extra by setting a couple preferences and connecting with Facebook. Also, I believe the treasure hunt is still running – you can get another GB by completing that (and there’s guides online if you don’t want to do it yourself).
No, the treasure hunt is closed to new entrants, but they say they’ll make another one in the future.
