Problems after GB update

I called my girlfriend's droid x2 this morning to wake her up. Her alarm had gone off, she couldn't shut it off, she couldn't power it off so she pulled the battery and missed my call.

I am reporting better battery life and *improved music play. DX2. Music still choppy when completing other actions with phone. Stand alone music play is seamless (poweramp full version) and clear. Battery life is my biggest plus. I've noticed some email notification differences using gmail label notifier but minor issues at worst.

Side question, what is a launcher and why do I need one?
 
My phone is definatly more responsive. But I have had it reboot while in the car dock, when playing music mostly.
 
i have been having issues with the keyboard with the update,, it doesnt work in chat sites i used to always frequent, it will pop up when i tap the input field, it shows the keys light up as i touch them but nothing shows up on the page, totally kills the phone for me. the screen still has the ghosting as i move from page to page and the phone has randomly rebooted a couple times and froze up during calls since the update,, i got verizon to exchange it and the new one still has the same keyboard issues,, seems to be a motorola issue since my friends htc phones with 2.3 work fine
