no, but one shouldn't expect n810 to perform well as a music player in hi-fi audiophile setup. if you need that you get dedicated device with good DAC like 5.5 gen ipod. same with gps or any other feature. when you get universal gadget like this for it's price there are compromises to be made. i'd be very happy if you can point me to device with the same feature set and expansion capabilities for the same price.

but i'm sure it's possible to improve current aquisition/reception quality in software and i'm all for augumenting it with wifi bssid based location info.
