The downside to having multiple computers is synchronization. Dropbox is the perfect solution for these situations.

With Dropbox you can seamlessly synchronize contents between several different computers – even mobile devices – no matter where you are. This means that you can use Dropbox not only to sync files between computers, but also to share photos with friends or collaborate in a common project with your workmates.

Dropbox is dead easy to use. All you have to do is install a small client and from that moment on, you'll have a special folder inside the My Documents folder. Anything you drop here will be synced in the background with your public dropbox profile – and therefore accessible online. Dropbox currently offers 2 GB of free storage, which should be enough to share quite a bunch of files.

Worried about privacy? Fear not. Only computers you link to your account will be able to access your files. Also, Dropbox keeps track of changes, so that you can access previous versions of a file. In a way it works as a backup tool as well, because it keeps copies of your files.

Dropbox has a main drawback though: it's painfully slow. Yes, it works in the background and yes, you don't have to be checking the uploading rate every ten seconds, but 30 minutes to upload three photos is simply too much for me.

Dropbox is an easy, handy tool with which you can sync files online, share them and have them always at hand.
