People looking for "openness" is a very small margin though. And in a way, the "open" factor, after some time, works against it, rather than for it.
I was Android fan for a long time. Couldn't imagine switching to something like IOS that didn't have proper multitasking, or even basic features like a quick wifi, 3G and bluetooth toggle on home screen. And then - as "douchy" as it will sound - I got to the point where my life got really busy and mobile communication became in professional terms really serious matter, and I had a very, very little time to constantly play around with half baked flashes that would often leave my phone semi screwed until next patch for days, randomly crashing overclocked features, sometimes laggy governors not waking up the phone quick enough etc. What I took for granted in android platform became a bit of a chore, required constant maintenance, attention. I could no longer allow my phone to lose a text message thread or crash while answering call. If my call was accidentally dropped I could no longer trust that it wasn't because of a kernel module that some student working via forum form a dorm in Prague borrowed in the middle of the night, from a semi working Singapore rom made for a completely different phone, for his custom compilation of what is, on a best of its days, a beta OS anyway.
I realised that until I am able to tweak and customise, I will always tweak and customise. And that tweaking and customising will always lead to seldom, minor, but definite instability of what was, at the end of the day, no longer just casual and social communication tool. And I will regret it. So I moved to IOS. It's fast enough out of the box. It's got enough apps out of the box. It does most of the things, good enough, out of the box. Cannot tweak it therefore cannot break it or make it unstable. Works well ever since I switched. Many things work better, as it's a 100% match between hardware and software. Camera for example, no more lagging, no more searching for better app, no more hunting for focus when reading barcodes, point, 1 second, done. No more car bluetooth loosing sync with the phone after few hours. No more card cleanups, corruptions, repartitionings and running fscks before updates - there is no card, there is no problem. No more worrying if the next update will soft brick the phone. So on, so forth.
Though that said I very much doubt jalibreaking is any harder than installing a custom ROM if that was the way you wanted to go.
