“Two possibilities exist: either we are alone in the Universe or we are not. Both are equally terrifying.”
From Clarke, but that was quoted at the beginning of some really brain-cancer-inducing movie somewhat recently. Perhaps this is why I cannot recall which movie.
Can I run a WebKit based browser on FireFox OS?
From my very cursory understanding of Firefox OS I'm guessing that's a no - there are no native apps at all. But my point was, you can run Gecko on Android. You can't on iOS. Chrome on iOS is really just a wrapper around UIWebView, you don't get to use the V8 Javascript engine. Whether this is reasonable due to security issues or just plain anticompetitive is debatable.
You can swap it out if you've jailbroken, or simply write your own app with any engine you like (which works fine for personal or enterprise use).
This point I've never quite fully understood - people keep complaining about how insecure Android is (which is a debate for another thread). Yet when discussing shortcomings of iOS, the answer is always "jailbreak" (which might or might not be available, tethered or perhaps not). As it is, at work I've been developing an app for iPad that is HTML5-based. And the performance is worse than what Mobile Safari would offer. If you want your HTML5 app available on the App store, this is a fact you'll just have to accept. This is also the reason you shouldn't expect Firefox on iOS anytime soon.
