Good to see mediabox on the N900; it was an app I used heavily on my N800. One feature that I liked on the old version which I can't seem to find on the new one was the ability to delete playlist entries from a selected point to the start or end of the playlist. Apart from that it seems pretty solid from what little I've had chance to use it so far. Regarding Bobby's comment about volume, it can be adjusted with the system volume control (tap in the status area at the top and it pops out with other menus). There seems to be a problem though, as the volume resets after each track; I think this might be a system-level issue though, as it's the same in Panuccu. With both, just tapping on the volume control (even without moving it) brings the volume back up.

Needs some improvements; the UPNP feature is extremely useful and well implemented (however, it needs work too).
