So-called "pros" ? I assume you are a So-called "fanboy" and you think you can do everything on your iPad or mac mini. People are entitled to opinions, just as you are. Having a pro devision is like engine, brake, tire, oil manufactures participating in F1 racing. It is R&D and the technology moved forward in the pro devision trickles down to those toys you love using.
I'm not saying the numbers are wrong... but where I am, I have never seen anyone (with the exception of my wife who bought an 80 $ piece of junk tablet running android) use anything but iPads. I'm serious... I cant wait to see someone show a "high end" adroid tablet they actually use.
