Been using the IIs since November also. So far, one of the best handset I ever used, which replaced my previous workhorse N7650.

Keyboard loose seems to be a problem for quite a few people although I found my keyboard to be relatively tight even till today and I use it a lot with constant open/close. Perhaps putting it into a case like the Krussel case will help reduce the loose feeling..

I faced the problem of not being able to hear the B-party's voice too...most of the time..not a big issue, just a quick soft reset will solve it. I rarely face this problem coz I reset my device almost every night. My clock is still consistently accurate after each soft reset. Although I only performed a hard reset once, it should be normal for it to fall back to a default date. I do believe there should be an option to sync your PC time with the XDA.
