few comments...

- Login takes quite long... sometimes it shows Updating playlist sometimes not.
- Song glitches when display dims out.
- Play-button, mostly it works for me as pause - button, but if i select a song and press play-button nothing happens... i can start playback only by double clicking a song.
- It seems that sometimes after a 5-6songs, Qtify crashes... well, only once it has done that.
- Qtify works on my home wlan, but not in my work wlan... work sucks
- the playlist down-arrow is a bit small to be used by fingers.

- i tested running qtify in 3G - network in my car through FM-transmitter, oddly the sound seems to be better than the default player on N900

when the login/playing problems are solved, just add shuffle-play and offline mode ...should be no problem, right?
