"Other than being massively expensive and having no real advantage in a meeting over a projector? Yes, let's design something that requires me to stand in front of it in order to interact with it, thus obscuring the display from the audience. Truly an idea worthy of Balmer (and apparently now Sadnads).
It might make a good novelty display system in the lobby of certain hotels or convention centres. However, that's a very limited market. A small specialist manufacturer might make a good, if obscure, business out of something like this, but as a division of a business the size of Microsoft it's pointless."
You have no idea what you're talking about, do you?
Firstly, it's around half to 1/3rd the price of similar display walls, while being considerably better quality. Secondly, anyone working in the construction industry can see the advantage of a multi-user touch-screen that is big enough to display A1 plans in full size. It's not really for show-and-tell powerpoint bollocks (though yes, many execs will probably user it as such). It's a productivity device that engineers and architects are going to go completely apeshit for. Anyone involved in Building Information Management workloads will be falling over themselves for this thing.
