My Observations

I followed the kernel forums rather closely, and I have followed this forum since the beginning. I only wanted to provide my observations because I am reading some negative things about the new kernel that I have not experienced, and if I say something that helps one person, it was worthwhile. I have ran the previous version of epinter's CM10.1 every since it was released, and I did not even think about playing around with the new kernel until he compiled it into the new ROM(May 20, 2013).

First off, let me say, "Wow and thank you" to all of the devs and testers that helped with the new kernel. Even in the alpha state, CM10.1 appears to be so much better than it was on the old kernel. It is nice to be able to watch Netflix and Hulu again. My observations:

1) Crashing - On the previous version, my phone crashed or locked up at least once per day. I would have to remove the battery to force it to boot, and many times, I would have to do it twice because it would get stuck on the Moto logo. The new ROM has not crashed or made me reboot a single time since Monday. I have a 32GB SD card in mine, and I have not experienced any issues with it. I don't know the brand or the format type, but I can check if anyone thinks it is relevant.

2) GPS - I had a problem yesterday on the new version with the GPS. It would lock in GPS Essentials, but it would not give a good fix in Google Maps. I tried epinter's suggestion ( http://xdaforums.com/showthread.php?p=41673652#post41673652 ), but it did not work for me. I did get it to work by going to Settings and Location Access and disabling "Wi-Fi & mobile network location".

3) Battery Life - My battery life seems much improved on the new version. Right now, I have been off the charger for about 14 hours and I am down to 70%. I have no measured comparison between the last version, but I know for a fact that my battery would be almost completely drained on the new version. By the way, I am using my original battery that is over two years old. For people experiencing rapid battery drain on this ROM, I would ask them to consider the type and age of the battery that they are currently using. I have bought several replacement batteries, and I can personally tell you that the replacement batteries are not equal quality. As a matter of fact, most of the replacement batteries that I have bought do not perform as well as my two year old battery. There are some vendors selling genuine Motorola BH6X batteries on ebay, and they are crap. The batteries even say BH6X on the side, but they are a little thinner and the label says 1500 mAh (the orginila batteries are rated 1800mAh). I honestly doubt that they will even provide the 1500mAh on the label.

4) Application Updating - This is one bug that was present in the previous ROM that has hopefully been resolved in the new one. I only mention it because it is something to watch for. After running for a month or two on the previous ROM, I would start getting insufficient memory errors when updating certain applications. I tried Link2SD, Lucky Patcher, and several other ideas. The only fix I found was to reinstall the ROM. I actually had a couple of apps that would not update just prior to installing the alpha ROM. I will be an optimist and assume that this problem is no longer present.

5) Skype crashing - My Skype has crashed a few times, but Skype for Android has never been a stable product anyway. The problem may be related to the front camera bug. Regardless, it is a very minor issue for me, and I know that there are problems with the front camera so I am do not plan to even try using it until I read the the problem has been fixed.
