Hardly any?
OK, this is purely anecdotal, but I threw a big party last weekend, as we do every August Bank Holiday. Just about everyone who comes along is connected to the IT inductry at first or second remove, and there's a lot of gadget freaks, because those are the circles I move in.
I didn't do a formal count, but I know for a fact there were three EeePad owners, one HP Touchpad owner (full price), two HP Touchpad owners (fire-sale, and probably thus not relevant), one Galaxy Tab owner, and one owner of multiple cheap chinese knock-offs. And about 7 iPad owners.
From that extremely small sample, I would have to draw the conclusion that Apple aren't having it all their own way.
