Those are all phone OS's you listed. I was talking like desktop computer OS's like Windows 7 and Snow Leopard. When I get a computer I want it to function like a computer, not a glorified phone.
I'm pretty sure iOS, Android and webOS are also tablet operating systems. They suit tablets well.
If you're buying a tablet, it could have Windows 8 on it, and you'd have this new touch interface, but you'd also have the ability to go into the traditional Windows interface. If you're on a desktop, you'll never even have to see this touch interface. I don't know what you're bitching about.
