I have been using the DROID since the 6th, and I was very pleased at the audio quality of the device. I do agree that the audio amp is a little weak, so perhaps with higher impedance headphones, you may want to suppliment the audio with a headphone amplifier like the Fiio E5. I found the sound quality, not volume, to be superior of the N810, so using streaming audio it's been nice. I too hope that the N900 has good sound quality for both headphones and and external speakers. Especially since the N900 is such a media-centric device.
