This way you could give a presentation (and make annotations), show movies on your tablet and stream it to your PC/laptop which is connected with bluetooth (in e.g. a classroom) with no need to go to the PC.
Has anybody used this setup?
As a teacher it would make a smartboard out of my tablet (which i would buy for this purpose, amongst few others) and a simple bluetooth dongle which I could plug in the school PC.
Looks simple to me, but probably isn't as simple as I imagine?
I'm even prepared to pay a fee for an app if this is available.
