With the advent of crazy new media players like the iPod Touch and Archos, I think the taxonomy structure should be modified a bit.
Right now the stucture is as follows:
Electronics->Portable Media Players->(MP3 Accessories, MP3 Cases, Docking Stations, MP3 players)
- Electronics->Portable Media Players->(Player Accessories, Players)
- Player Accessories->(Cases, Docking stations)
- some products will be categorized just in Player Accessories, which new subcats being added as necessary
The properties specific to MP3 players are as follows:
I think Capacity should be renamed to Maximum capacity, and Player features CAN stay, but I don't think it's very useful anymore. Ideally it should be cleaned up. And we add a new kind of property: Storage types, which would include hard drive, flash drive, and compact flash based.
