Guys...I've taken a look at the thread and I'm unlocking it but I'd ask everyone to please keep the tone of the thread positive. I understand sometimes these tech issues can be frustrating and sometimes it's easy to get out some of our frustrations on anonymous people in a forum. But that's not gonna help get the issue resolved any sooner so let's keep the tone positive.
Now as far as the bluetooth issues with the headset, I think there are many people that are having some bluetooth issues since the 4.2 update and since Google is aware of the problem we'll just have to wait for them to issue a fix. When Google or any company for that matter offers an upgrade to their software there is always a tradeoff of getting great new features with the possibility of there being a glitch or two that they didn't expect or foresee. Google has had a good track record of recognizing these glitches in a fairly timely manner and issues fixes for them. I'm sure this will be the case with this bluetooth issue as well.
Every company...Apple included...has glitches from time to time with their updates. Look at the fiasco of Apple's latest mapping software that has been written about all over the web. So since no company is immune to these kinds of issues and glitches as it's simply a part of progress...there's no point in getting angry or bent out of shape about them.
As owners of a Nexus 7 you are on the cutting edge by getting all the latest updates to Android first...before any other device. Part of the fun of owning a Nexus device is knowing that we are getting the latest and greatest Android version before anyone else. It's inevitable that there are going to be software glitches along the way but keep in mind we also get the fixes first as well...so in the end we still come out ahead. I'm confident that Google will fix the bluetooth issues and any other issues with the latest 4.2 update soon...just like they always do. Meanwhile we get cool new features like multiple user support...which you won't find on any Apple product
