Dropbox lets you bring all your photos, docs, and videos anywhere. The free version gives you 2GB of space to use, though you can add several more MB of space by clicking the GET FREE SPACE options linked via their desktop interface on the right site.

HOWEVER for the BIG BONUS, be sure to download the Dropbox App via the Google Play store to your Android smartphone. If you opt to sync pictures, they will give you an extra 500 MB OF SPACE FOR FREE!
