Here are my suggestions for the NW-E40x/50x series: -rearrange the main display, move the track counter to the last line (where the time and battery indicators are) and make the second line (displays the artist) scroll. -I want a five band equalizer, but I don't know if it is even possible with the processing power on the player, volume normalization would be nice too. AVLS is rather useless. -More accessories! Arm bands, lanyard type things etc. -quicker fast forward, its just too slow even after twisting the thing for 10 seconds. -have the screensaver kick in after a certain amount of time, just like the power save feature. -ok this one is a bit hard to describe but I'll do my best. There is a bit of light "leakage" on the right edge of the OLED panel, it seems the light is being reflected within the piece of glass and escapes through the edges. I'd like it if the edges are masked off, covering all but the viewable area of the screen. Just aesthetics. -have the amount of time remaining on the song displayed, somewhere, anywhere. - The earbuds included with the player sound good (at least to me) but they are very, very uncomfortable. So much so that I had to remove the plastic surrounding the earpieces, now they feel okay, but just look halfassed because you can see bare metal around the edges. In short, just make em perfectly round, and maybe include some foam covers. Thats about all that I can think of at the moment.
