You think a couple of devs leaving the iPhone means anything in the grand scheme of the app store market? Not a chance. For every one that leaves, hundreds (thousands) more join, some who are high profile, and some who will be.
Impact of some devs leaving the iPhone (and NOT going to other mobile platforms, too boot!) is virtually ZERO. The iPhone has too much momentum, too much popularity, too much mindshare, and too much promise to be derailed by that. The devs live with the app store or they don't. The vast majority (and there are many of them), have chosen to live with it. And most importantly, Apple is improving the App Store processes. It isn't perfect, but it sure as hell is the best out there. So a few devs leaving the iPhone isn't really news, and is at best, an indication that the app store is imperfect, something we've known for a while. Apple has been working to improve it, and that's something that the competition should fear.
So why is it big news when devs leave Android, or just aren't interested in the platform? It's big news because Android has received a great deal of publicity, has been spun into the Next Big Thing, is desperately in need of developers and some serious attention, and here's a high profile developer that just isn't interested. Android is the one platform that has been singled out by pundits as the preeminent iPhone rival, and it is in dire need of developers. Given all the hype, the disinterst of Gameloft (and likely others) seems to run counter to all the hype, especially the hype about Droid, which surprisingly, enjoyed at best a lukewarm reception. The trials and tribulations of iPhone competitors are always big news, for obvious reasons.
Delusional much ? The impact is the same for Android and iPhone. In fact, I'd think big name devs leaving iPhone is much worse, since as you say, it's better established, has more mindshare. Why would you leave it if it was such a winner ?
Especially when we're talking about guys like Rogue Amoeba...
You can try to spin this as positively as you want, the fact is, it's not good for either platforms when devs leave. It's also showing quite a bit of bias for Macrumors to put this Android news up on the front page, but to hide the iPhone devs news deeper on the site.
Why am I arguing with you anyway ? You're the biggest Apple fanboy on this site... They can do no wrong (but yet they are 3rd in market share with the iPhone and the first gen iPhone had as much problems piercing the market as first gen Android devices did).
