Earlier quoted context omitted.
You and many others are missing the point of why this is epic. When was the last time a device with so much market penetration and insane adoption rates allowed video chat in such a simple way? The reason it is epic is because this is the first time it'll actually work. Who cares about N900s? Does my grandma know what an N900 is?
Does your grandma have an iphone 4G hooked up to Wifi, and a friend that has an iphone 4G hooked up to wifi? My father has an N900, and he video calls europe every day. I didn't need to show him how to use it or anything.
Hooked up to Wifi? Is that hard to do? Or are you making the point that it's wifi only for now. Jobs specifically stated that they are working with carriers to support it. That means it's coming. Baby steps. This is what Apple does. We don't always get the full package with iteration 1, but when it does come they do it right (see copy/paste, see multi-tasking).
I don't know a single person who owns an N900, and I don't know a single person outside of a very small group of tech friends who knows what one is. I'd guess that 80% of the people in my friends/family/work circles have Apple devices, most of which are iPhones.
