My biggest headache is that 'wireless hdmi' in advertising is not guaranteed. It doesn't say "wireless at 65 feet" - it says UP TO. That means, that if you get 3', then that falls in the range of 'up to'.
Certainly the article makes a great point of running your HDMI cable from the equipment to the projector location, but you might as well throw in getting the power to the projector as well since that's something most people aren't willing to handle themselves.
I think BenQ has managed to get rid of their real clunker products and has some relatively decent stuff and certainly delivers for a great price, but if companies are going to add bells and whistles which go beyond basic projection, then those additions either need to be dirt cheap, or need to be brilliantly implemented. Perhaps this DOES achieve that goal, but if it doesn't, then that needs to be pointed out in testing and some real testing of the range of the WHDI needs to be tried out when this projector is tested.
Also worth finding out if the use of WHDI may somehow also impact EDID, though I would expect WHDI to be used on the output side of an AV receiver.
