Online space for backup, storage, and collaboration is no longer available at a premium. Blame it on competitive offerings. Mediafire offers of free storage and their new Android app could be the portal for filling up all those free gigabytes.
Have you ever got home just to realise that that the file you want to edit/work on has been left on your computer at school. Well Dropbox could be the answer; a central 'cloud' storage online - save there and you access it anywhere.
