I'm not an iPad user and I really love my N7 but I notice this lag occur a few times yesterday. I suspected that it was due to high CPU load but didn't have the time to investigate it.
It actually occurred while I was showing off the N7 on the DC Metro to an interested rider. I feared that this out-of-love iOS user may have been deterred by the momentary lag even though the tablet is otherwise awesome.
I hope that this gets fixed in 4.1.2; Project Butter has made Android significantly smoother and I think this is just a rogue element in Google's aforementioned "War on laginess".
Seriously? Given video proof, and without bothering to check for multiple supporting testimony from other affected users, you make cheap irrelevant accusations?
Sir, did you read the article? The author makes no mention of even anecdotal evidence of problems beyond his single Nexus 7. You don't write an article about a single defect instance. A post in a forum maybe, and after there is evidence of the problem being widespread you write an article. Perhaps I should write an article about the rotten apple I bought yesterday and title it "Whole Foods Apples Rotten".
The evidence that appears herein is after the fact, and even so is hearsay and subject to selection bias.
It's funny how well your comment applies to the article author, yet you attack me.
I get the feeling that you only read the article and didn't watch the video because in about the third sentence he says "There have, however, been some sporadic reports of problems with the touch screen, and it turns out, the unit that I have received does seem to be affected. So, I thought I would show you what some of these problems look like."
He is obviously seeing other reports of problems and is presenting his own as a representative instance.
As a former Android user, I say that a history of responsiveness issues on Android devices makes me particularly sensitive to issues like this popping up on the latest hot new Android device.
Responsiveness is a big feature that pushed me onto iOS devices. Kind of ironic, given that it's the other way around on the desktop for me: my Linux machines are nice and responsive even on modest hardware, while my former MacBook Pro beach-balled and beach-balled. It took going entirely solid-state storage on the MacBook Air for OS X to stop driving me insane with responsiveness issues.
