an ecosystem that allows even more garbage onto their platform than what currently is possible (anybody getting into the phone business today and does not follow Apple's App store model is dead in the water).
I don't know just how important the app store is. I'm sure it makes Apple a lot of money, and helps convince techies and gamers to buy Iphones, but techies and gamers are an awfully tiny portion of U.S. consumers. Does the average person buy an Iphone because they want to play Angry Birds on the go, or do they buy one because Iphones are status symbols, make you look successful or important, and "hey you can download an app, well I guess I'll try that it's just 99 cents."
Case in point, via opposites: I've been carrying around my 3DS all the time not just to play games, but also to take 3D pictures, which as a parent of 2 girls I tend to do a lot. I was on a field trip last week with my oldest daughter, and one of the other parents, the only dad who's as young as me (32), says "Hey, I didn't know you could buy a DS with a camera now. That's pretty cool." Oh yes. This guy knows what a DS is, but not a DSi.
Another horrifying story: I'm taking pictures of my daughter at her preschool's easter egg hunt today, and a bunch of the other parents are curious about this funny looking camera I've got. So I explain that it's 3D without glasses, show them a bunch of photos I took in 3D, show them how to watch with the sweet spot, etc.. They are amazed. Then one of the parents, some doctor, says "OH, that's a game, isn't it?" Pointing at my 3DS. In a very, very disappointed, disapproving tone of voice.
So, to sum up? If I had a Nintendo phone, other adults would point at me and say "ooh, he likes games." If I had an Iphone, they'd say "Wow, you must be important or rich. Or both."
Please, please don't make phones Nintendo.
