First of all its size, weight and resolution (I wasn't aware that there were full HD projectors on the market, I'm sure here in Argentina it wil prove rather challenging to get my hands on one) are the key features of this product. I would love to use it, not only for games a and multimedia but for studying in groups. I am studying electronic engineering and this projector would be quite useful (definitely better than sharing a 15" screen with 5 mates).
Good Luck!
