Here's how it would go.
Launch Day: Programmers are notified that they will have to rewrite their programs to work on the Nano. Everyone whines, bitches, moans, and claims that the Nano will fail within weeks without programmer support. A lot of them vow not to buy it or program for it.
Fifteen minutes later: The first fart app for the Nano is ported.
A week after launch day: Programmers of apps that make obscene amounts of money grudgingly announce that they're working on porting their apps.
Six months after launch day: The Nano 2nd generation is announced. All apps have either been ported, or portable equivalents have been written.
You know that's how it'll go down.
