There are MP3 players (more like video players) with as much if not more space than my iPod 80 GB, but they're bulky, and heavy.
I didn't buy an iPod because it was cool, but because it was the more convenient, despite Apple not supporting Linux.
Besides, white is NOT the new black, shiny black is still the 'best' color, the one introduced later to increase sales. White is the 'introductory' color. Black iPod was introduced later, black DS Lite was introduced later, black Wii will be introduced later. Black PowerMac (or whatever the names) are more expensive than the white one, just because of the color. Perhaps this color costs more to make.
Erik Aston : reducing consumer electronics and software to the 4 companies you cited is nonsense. These companies would not even be succesful or exist without several others you missed (IBM or Philips come to mind, without these two, the four wouldn't even exist).
