Unfortunately, that seems to be a lot of people, at least in my experience. Almost everyone I show my N900 to expects it to be a capacitive screen, even if they don't know it's called that - I can tell from how they try to use it. As soon as I say that it's "different than the iPhone", and give them the one-sentence dumbed-down explanation of the difference in technologies, they get it almost right away. For that matter, look at all the comments here on t.m.o. and elsewhere, saying that the touch panel "stinks" solely because it's not what they're used to (e.g. the iPhone). I'm not saying that this is a valid design reason not to use this feature, but just that people's expectations seem to be pretty specific in this area; for a lot of people, the iPhone was where they first saw multi-touch, and their whole concept of the technology is based on it.
I'm not arguing with you, but I thought I should point that out, as silly as it is.
