Combustibility is a good word... because that's how I feel on Android most of the time... " just a matter of time until something goes wrong " kind of though in the back of my mind.
But yeah, Apple has that edge because they have such limited hardware that it gives them more room to be able to polish of drivers and bugs and get everything the way it should be. But personally after jailbreaking, there isn't much you can't do to it, in terms of customizing ( GUI, Lockscreen, Layout/Size of icons, Dock ) everything about the "feel" of the device.
I meant to say customizability. silly auto correct. I've corrected the post. I can see the iPhone and iPad taking the corporate niche for mobile devices while android is going to trend toward the more geek and or enthusiast markets. I feel it's kind of like linux in a way fairly user friendly but not fully mainstream.
