After getting an iPad recently I 100% disagree. Android has gotten to the point it is very functional OS for me. With mouse support, great USB support, great file managers with network support, Office support, emulation support, etc. what you get with a non-rooted Android phone/tablet functionality wise is very close to a real OS like OSX or Ubuntu. iOS feels like a toy OS in comparison because it has no decent file management even if you jailbreak (I would pay $50 to get the free Es File Explorer on there), no mouse support, and the fake multi-tasking outright sucks. The only functional advantage for me over Android is that I can use a Wiimote with it, but only when I completely blow away the iOS bluetooth stack and replace it.
I love the iPad hardware and I would pay $100 extra for it to run Android because iOS is so non functional for any person who actually knows how to use a computer and doesn't need a compute appliance. I have basically accepted this thing will be a glorified web browser and game console because even with jailbreak what I can do is so limited. I understand that for 99% of people iOS is just as good or ever better because it has some fitness or social network app they like, but to say on a nerdy forum that there is very little Android can do that iOS can't is simply wrong.
