Frasier Speirs, one of several well-publicized developers to leave the iPhone over objections to Apple's App Store policies and controversy surrounding app rejections, has decided to return, post iPad, and his reasons are intriguing:
I suspect that the days of everyone buying a MacBook to get online are soon to be over. I've already written about how I see our three-Mac family turning into a one-Mac, three-iPad family over the next hardware cycle and I imagine that scenario repeated industry-wide over time. Already the ratio of iPhone OS devices to Macs is 5:2.
He believes Apple can and will reject apps, and that the frontier days of computing are giving way to the mainstream, appliance future.
iPhone OS is the first mass-market operating system where consumers are no longer afraid to install software on their computers (I’m not counting read-only media software platforms like games consoles here). In a conversation recently, a friend recounted a scene that he passed by in an airport. Four fifty-something women were sitting at a cafe table discussing the latest apps they had downloaded on their iPod touches. New software can’t break your iPhone OS device and, if you don’t like it, total removal is only a couple of taps away.
Speirs also thinks iPads are cheap enough you can buy each year's new model and still save money compared to traditional computers. And he wants into that ecosystem.
