I've found the audio streamer appears to tie up the system resources to such an extent that even simply trying to adjust the volume is painstakingly slow - never mind trying to multitask whilst listening.

Another observation - when audio streaming the backlight remains on full brightness - not sure if it did this in 2006 or not, but at least switching off the backlight would conserve power...

Placing the cover on seems to activate some sort of sleep mode, but the battery is flat in the morning...
