Ever since the advent of Project Butter, Android is basically meant to be on a par with iOS when it comes to responsiveness, right? Has anyone found this isn't the case? I know when I was looking at videos, trying to decide whether to get the Nexus 7 or not, the reviewers would show off the responsiveness of Project Butter as a key feature. To do this, they'd often flick between home screens or open up the browser and do quick flicks up and down the page. The Nexus, for the most part, does perform those actions very quickly, it's when you slow things down that it seems to fall apart. The vast majority of the time I do my browsing by placing a finger on the screen and dragging up very slowly as I read down the page. The Nexus stutters and jerks constantly doing this, whereas the same action on an iOS device is perfectly smooth. It's not terrible stuttering, it's like the difference between scrolling in iTunes on OS X and Windows- Windows scrolling seems like it is taken in 'steps', where a song at a time goes past if you scroll (or 2 or more, depending on your scrolling speed), whereas OS X feels perfectly smooth, without the stepping and jerkiness found in Windows. The Nexus feels like Windows scrolling, slow things right down and it seems really jerky and jumpy, but doing quick flicks around seems fine. Now that I've noticed it, I hate it. I was really looking forward to getting a Galaxy S3, but the jerky scrolling will send me insane if it's on my daily driver. Are all Android devices like this or have I got a bad Nexus unit? How have you found Project Butter- a success, or does it still leave a lot of room for improvement?
