“We define everything that is on the phone,” he said. “You don’t want your phone to be like a PC. The last thing you want is to have loaded three apps on your phone and then you go to make a call and it doesn’t work anymore. These are more like iPods than they are like computers.”
I understand what Apple's after here - a mobile environment is a whole lot less palatable when it's got crashes and glitches like the desktop and laptop world. But, I have been known to [run Linux on my iPod](http://ipodlinux.org/Main_Page), so I like to crack the closed shell on devices that go in my pockets. Hopefully the iPhone's lockdown is more of a "keep out" sign, rather than a sealed vault.
