Box 1.5 has been released on the Android Market, adding the ability to piggyback on apps that create and edit Office documents and save those files straight to the cloud — something you could naturally already do on a PC using the Office add-on. You also get a widget to keep track of your colleagues' latest changes to documents and the ability to upload files from anywhere on the phone. Not to be confused with Dropbox, Box targets business users with its mix of cloud-based file sharing and Google Docs-style collaboration and editing. You can get the latest version from the Android Market right now.
