With more people toting Android tablets, their potential as remote access devices grows, as well. Splashtop 2 Remote Desktop is a great way to operate a Mac or Windows PC via an Android slate. It lets you run desktop programs remotely, view and edit files without fussing with transfers or syncs, and even watch HD movies (depending on the speed of your Internet connection, naturally). The personal edition is free for noncommercial use, but you'll want the Anywhere Access Pack ($1.99 monthly or $16.99 annually) for remote access via the Net. Business and enterprise editions are available, too.
