I went to the Nokia store in Chicago today, so I have a couple of goodies to share from some polite conversations I had with the reps.
All of the prices mentioned in this thread are the same prices at the store, and coincidentally, I looked at the two of those specifically because I noticed the prices were so much lower than they were.
Unfortunately, Nokia will give a refund for the phone's current price for which they are selling it now, not the price it was originally purchased. This was covered in another thread, and it kinda sucks.
The N73 they have there is silver/plum and it has a bit more detail to it than my older one did. The silver keypad has a chrome joystick instead of the greyish one that was originally launched, though the display version I played with still had a bit of give on its joystick. The rep said they have made improvements to it since the original batch, but ultimately it's still pretty bad.
I don't know if the N73's they carry have a different RM number. I didn't even think to check.
After speculating about a spring-assisted slide from some of the older N95 videos, I can confirm from talking to the reps that the phone is indeed spring-ASSISTED. It doesn't snap open like a Samsung, but it is designed to make sure the device slides smoothly and doesn't go too far in either direction.
Though they couldn't give me a definite answer, they're really hoping that they'll be getting it this month. It sounded like that was the plan, though they can't say that since it's still subject to change. The estimated price we talked about was $799, but they don't really know that for sure either. I'm taking both pieces with a grain of salt. It took them forever just to get an N73, so I wouldn't expect to see a wall for the N95 until 6 months after it comes out or so.
