Hi folks, I have an Asus EP121 but am looking for a cheap, small, light (7" range) tablet for a specific purpose that should be simple, but is proving complicated. I work in a university where every classroom has a projector and teachers plug their latptops into patch-boards to project powerpoint (with sound) for lectures. My goal is to plug a Win 7 laptop into the projector and then control the powerpoint through my tablet using Powerpoint presenter mode. So I need three separate things: - ability to link the tablet and pc wirelessly with enough range that I can walk around a normal sized-classroom while speaking - tablet that will run some version of Powerpoint - same tablet must let me treat the PC as a second monitor (so that PP lets me run presenter mode) I'm open to any combination of hardware/software for this, including any apps anyone can suggest, but my strong personal bias is to stay away from ipads and/or Mac laptops. I think this limits me to Android tablets, but can't seem to find any appropriate apps. But is the ipad mini even an option to control a PC laptop? And, since this is the only purpose for this tablet, I'm not looking at the Surface Pro or other full Windows tablets right now - too expensive. I think I could use Avatron's Air Display to link my EP121 with a laptop, but it's big and heavy for holding while walking around a classroom. Something 7" would be ideal. Does anyone have any suggestions, or am I just stuck until Microsoft releases an Office for Android? Thanks in advance for your thoughts!
