Welp......After installing, and messing around with JB for most of the day, I wasnt impressed. It seemed to lag a bit every now and then. I did 2 cache wipes, or whatever its called, and it seems much better now. About what it was on ICS, or a very little bit better. I DO NOT like how after a call ends, it takes you to the recent calls list, rather than the home screen, as it did before. The camera does seem to be a bit better with picture quality, with much better low light pics.
The very existence of flamethrowers proves that some time, somewhere, someone said to themselves, "You know, I want to set those people over there on fire, but I'm just not close enough to get the job done."
