I really like my Dropbox. It's just so convenient having my files sync'd up to the cloud. It's great to have a public folder for sharing larger files with friends and colleagues too. Now, the Dropbox Android app has been updated to a new beta version and guess what? They'll give you 5GB free for trying. The main reason for the beta is to work out the kinks, but you need users to encounter those kinks for you to fix them. That's why they're encouraging more people to get the new Android app.

Note: You don't get the 5GB of cloud storage right from the get-go. Instead, you get 500MB on the first sync. After that, you need to automatically upload additional chunks of 500MB to grow your account in 500MB increments.
