I am having issues. My phone was working great, initially, but since I started tinkering with settings to help troubleshoot battery issues, I actually started HAVING battery issues.
On top of that, I have 3 audio issues that are problems... can't play WAV sound files (voicemail attachments from my email system that worked great on the 900), a TRIPLE ding (two text + one email notifications) while on a call (instead of just one email notice), and music does NOT pause automatically when disconnecting headphones.
I have to say that there is definitely something quirky about this firmware release, and I can't tell if it's Microsoft or Nokia to blame yet. Whether I keep this or switch to an 8X remains to be seen on how the companies handle these issues.
