I just took Angry Bean for a test drive.
It was a bit inconvenient for me to make the switch because my customized deodexed stock 2.95 rom will not boot on 1.50 or 1.04. After flashing hboot I had to remove the battery and delete the hboot from the root of my sdcard. It would have been easier if I had used fastboot. After some messing around, it did boot.
WiFi tethering worked via the built in app. 4G worked, but it is not convenient to enable. The led stayed green all the time, I don't know why. I could not change the dates in the data usage area of settings. It seemed stuck on 30 days ending with today. No Frills CPU reported 1512 Mhz, reducing the need for a kernel swap.
I guess now I know why some of the launchers look the way that they do since they all must have copied the look of 4.2. I can't say that I am a big fan of sense, but it doesn't bother me either.
Since my stock based ROM gets great battery life with Mirage kernel and it has some crucial mods that I like (30 step volume control, dim led's, hyperlinks) it is difficult to get me to budge off of it, so I reverted.
However, I have tried many ROM's and Angry Bean looks like one of the better choices out there. It would particularly appeal to those who don't like Sense, want a version of Google Now that is not crippled, or just want the latest thing.
