N900 matches well with "Nokia MD-310 Wireless Music Receiver"

Thanks to Wifi networking it streams music from the NAS or internet radio over bluetooth (via MD-310) to the living room hifi chain.

The N900 internet radio buffers the audio stream more efficient than the Symbian or even a dedicated Airstream 10 radio (the 2 latter experience buffer problems and drop outs).

Yes this matters when the internet connection isn't all that fast (cheap VNPT ADSL in Vietnam)

This way the N900 basically became remote control for the HiFi chain as I have lost my JVC original but thanks to Pierogi and the integrated N900 IR transmitter I can controle the volume also when not steaming from the N900 directly.

It is a luxury given to touch screen control a 90's surround amplifier and even be able to surf on the remote.
