I installed AOKP last night and all I can say is wow. It's very impressive. Good work. I didn't really want to go through the hassle of switching from ZVJ to ZVD, but so far it has been worth it.
After about ten hours of use after a clean install:
The unicorn boot animation looks too large, but I've never used AOKP before. Otherwise, booting up has been quick.
I have the power menu double pop. Long pressing the power button gives a "double" haptic feedback. If you press the back button, you can see the second shutdown screen that popped up.
The limited settings tweaks I performed in ROM Control were all buttery smooth.
I don't know if this is a bug or not since this is my first experience with the ICS lockscreen. It looks like at least one of the custom set icons doesn't appear on the lockscreen. For example, if I switch to "3 targets", in my mind that would mean 3 targets plus the unlock symbol. However, whatever I place in the Custom app 1 field doesn't show up. So I guess it means three targets minus one for the unlock icon?
I think it's an AOKP bug, but the lockscreen sound toggle switches the phone to vibrate regardless of system settings (unless it is hidden somewhere in the ROM Control?). Also, the sound toggle symbol doesn't update to show the phone is in silent/vibrate mode. Not sure if the icon is supposed to change though.
Not a huge deal, but the clock lag is there as noted. However, if I install FancyWidgets, the fancywidget clock stays up to date while the system clock lags. Sometimes it updates instantly, sometimes it takes a minute.
I haven't fooled around with a lot of apps, but my standards all seem to work without any problems. No problems with TiBU or the Play store.
The reason for my switch was due to push notification problems with the ZVJ radio. I didn't receive push notifications after the phone was in standby/screen off for some undetermined length of time. I have another Optimus S with CM7 and push notifications are working great; I'm cautiously optimistic they will work well on AOKP.
Oh, and an FYI for others, I'm using CPU Tuner with a max of 729 and a min of 249 using smartassV2, performance, and powersave governors and everything has been steady so far. Fingers crossed.
TL;DR
Awesome job. AOKP is really robust feature wise. So far, there are only some small issues with this beta.
