I think...
1. Despite months of hype and wild conjecture before the fact, this thing blows (appears to blow) the doors off everyone's expectations :-)
2. Rather than get into a legal wrangle over a name like 'iPhone' they should have just added it to the top of the iPod brand (first, photos, then video, and now mobile communications and internet access - why not?)
3. I want one... though I also worry about battery life & service $$$
4. I wonder if that touchscreen could be fashioned to read a finger/thumb-print...
