Correct. But it's a two way street, which I'm assuming you'll find out when you buy the iPhone 5 and half of your apps and games have black letterboxing on both sides of your shiny new 4-inch screen that Android first enjoyed in 2009.
On one hand, uniformity and reliability. On the other hand, flexibility and options. Try both, choose which one you like, and stop pretending one is hands-down better than the other. They're both good, but good for different people with different preferences. It's the beautiful part of the iOS vs Android battle... one of them doesn't have to win, and in fact, that's not what we should want.
If the developer is serious, they will quickly adapt to the new changes. You are talking as if Android phones have one universal phone screen size. I am fucking mad every time I create a android app, not sure how will it work on some XYZ android phone. So your argument is worthless when it comes to screen size.
Its not like android is superior to iOS and I highly doubt they will be able to match up even with the latest jelly bean.
In fact, I don't want google to ever dominate the mobile space. you already handed over your deskptop behavioral data to google now they want to own your mobile soul.
If you want to get targeted as black, indian, caucasian or jew, sure switch to android. Very soon you will be blasted off with behavorial ads and calling you out by ethnicity. Do No Evil my ass
