I'm a student studying Science at university, so i would mainly used the surface as a tool for writing my assignments (of which office would be a great help, as i only have openoffice on my pc) and researching information, i don't have and cannot afford a laptop right now, so the surface would be a great help for getting work done when i am away from home.
Of course i would probably also use it as a media consumption device when i can, watching films or tv while out or as an e-reader.
