Not having an 8700, and still going with the 7100, how would you compare the vibrate from the 7100 to the 8100? I've found the vibrate on the 7100 weak since the day I bought it. I routinely miss calls if I'm walking around on the streets outside, and end up walking around with the device in my hand if I'm expecting an important call. If 7100=8100 in terms of vibration, I could get over it, since I've dealt with it for so long anyway.
As for the MP3's, I'd likely stick with my iPod anyway, the 30GB suits my ADD much better.
