Trivia: the average number of games a Wii owners has is one. It's about six for 360/PS3 owners. This tells me that people who buy the Wii get wrapped up in the novelty, purchase one, and then realize it kinda sucks and leave it to sit in the corner. The iPhone is pretty similar.
You needn't be tech savvy for the Android phones. Little of what I love about the phone involves any kind of tech-iness. I have emulators, the camera is great, the screen is beautiful for watching videos, it integrates perfectly with my Gmail and Facebook.
And sure, no one cares about flash. Until they're browsing and run into sites that USE it. They may not REALIZE that they care about flash, but it's like saying no one cares if their car has a climate control system.
