Besides, I was referring to small UX/UI details (new swipeable gestures, new bits of polish here and there, new icons for core apps, new even smoother/slicker/amazing multitasking animations [much less disorienting than 4.1 in my opinion], etc).
I'm personally quite aware of the Bluetooth, etc bugs (though I can't reproduce battery issues on ANY of my Nexus devices, it's obviously an issue). They're obviously problematic. I understand why they replaced the Bluetooth stack but they didn't do a very good job of it.
I've been hearing this argument with every single Android release to date. Like your comment's parent, I try out another Android device every 18 months or so, and I still have yet to be impressed.
I haven't tried Jelly Bean though. Maybe it is really the release that makes everything better.
It's frustrating that this happened in Ubuntu as well. They spent a couple of releases focusing on fast boot times, and it paid off. A few releases later, and now boot times are slow again.
And I try out an iOS device every year or two, and I have yet to be impressed. The notification system is still inane, Mobile Safari still lags when scrolling, all your app icons still show up on your home screens, and you still can't use widgets on the home screen. When is Apple going to fix these glaring UX flaws?
> The notification system is still inane
No comment, haven't seen Android's version
> Mobile Safari still lags when scrolling
I haven't experienced this (iPhone 4 w/ iOS 5). Can you give specific URLs where this happens?
> all your app icons still show up on your home screens
You can make folders for your apps
> you still can't use widgets on the home screen
Not sure what this means (again, haven't used Android).
Things also keep getting better as apps convert their design to work better with Holo and Android 4.x. That is a gradual improvement that continues.
