I'm affected by the scrolling randomly pulling back. I had the same issue with my Samsung Galaxy Tab 10.1 (though this was more extreme). Here, the pullback could be solved using an app called TouchScreenTune, which allows to disable movement filtering, and lowering the minimum amount of movement required to register said movement. Doing this gave a much more responsive screen. The app doesn't work on the N7 though, but I suppose it would be possible to make a software solution for this 'issue' by someone with that kind of knowledge.
If you are having issues with your Nexus7, please indicate what they are by filling out the poll - there is no need for people to comment or start complaining, that's not what this thread is for and there are plenty of other places where you can post to express your unhappiness.
If you're fortunate enough not to be having any problems with your Nexus7 then there's no need for you to get involved with this thread at all.
The poll does not now and never will have a 'None of the above' option because that is not it's intended purpose and because that is not it's purpose, there is no reason for you to post in this thread either.
