I'm liking 4.2. I got impatient and did the framework trick, worked first time. All my apps seem to work. First time using android keyboard' takes a little getting use to after using Swype for a year, but I do like it better. Actually has a "." on the number screen! Like being able to manually enter words in the dictionary.
ssLauncher seems to work the same, but one added plus, is when adding widgets the text is a much better contrast.
Xscope browser has no issues. Flash works fine. Does crash occasionally, but no more so than it did on 4.1.2. PS: Browser only crashes with flash enabled. No crashes since I disabled flash, but flash works fine when I need it.
Not sure what everyone's lock screen problem is. Mine looks almost identical except for the bold hour, looks OK to me, although a different font might be better. Date is more readable. My koi live wallpaper looks good on the lock screen. If you don't like the clock, just put your calendar agenda there and delete the clock. My lock screen is on for about 15 seconds a day, so I don't really care what it looks like.
I don't use the right side pull down, use Widgetsoid so I get actual switches on my screen. I also like the left notifications. I have top bar hidden with my launcher, and now one swipe pulls down just the top bar, a second swipe pulls down the notifications. Works and looks much better to me.
Another PLUS... Amazon appstore looks much better! Everything is larger and readable.
I just noticed the time is in the notification bar, so I'm deleting the clock and just using calendar agenda. My lockscreen:
