that hasn't been true since long time now, especially so since ICSThat's plain out wrong. I'm on a Galaxy Nexus with ICS.
Scrolling and responsiveness are still major issues.
In 2012 I expect my phone to respond instantly and scroll smoothly, in all but the most extra-ordinary situations. iOS demonstrates how it's done.
On Android ICS my touches still incur a random lag that prevents me from tapping "by muscle memory" like on an iOS device. And I did spend multiple days removing all bloat, running the absolute minimum of background apps (JuiceDefender and a tool for the LED).
Likewise most apps can't even scroll a text list smoothly for whatever reason (lack of hardware acceleration perhaps, but as a user I shouldn't even have to think about this).
If you know any Android device that will survive a head-to-head comparison with an iOS device then I'd be curious to hear about it. I've bought the last two supposed high-end androids (Galaxy S, now Galaxy Nexus) and while there has been a noticeable improvement (largely due to the ridiculous CPUs that we get now) the overall situation is still a joke.
