Only had the N810 a few hours, the speakers do seem a little richer compared to N800. Haven't had a chance to really test it out though.

Was a bit concerned when Nokia decided to move the speakers to the side, but in fact I was pleasantly surprised when I actually heard stereo at an arms length! The only way I've ever managed this with the N800 is to hold it an inch in front of my eyes! Not exactly practical...
