Only true if one purchases a Lemur with the sole purpose of controlling Live

Not only true just for this case, true for general case.
now you can get dual touchscreen at 200$. Ipad at 500$ and 3M multitouch 20 fingers 22' (4x lemur touch area at 1500$)
with a soft such as usine, you're totally free to build whatever control you want, your monitor being usable for other stuff.
and there are such modular tools, even if less powerfull, emerging on ipad.
so, what's the point getting a lemur today?
absolutely no point, they have to make a cheaper true open monitor (portable) or they can GTFT with all their pricey hype.
