Ofcoruse they dominated with authority, they do so because before them no one had thought of a device that supported multi-format songs. Anything before i were MP3's. That isn't the case now with other products though, other products like Operating Systems are already quiet advanced and do their tasks, cellphones too are already quiet advanced, sure, the iPhone hit and it hit BIG but it serves diferent purposes and not everyone can live up to those purposes, I for one would not change my Nokia N95 for the iPhone because I simply like pressing keys and having a 5MP camera, other people are cotnrary to my belief and wouldn't trade their iPhone for my Nokia. In the case of the iPod and say, the Zune, it's different. I would never change my iPod for a Zune and when I ask around, neither would any of my friends and those who HAVE Zunes would rather have an iPod. Hell, the guy who has 3 Zune tatoos bought an iPod classic.
Hitting that type of market in all fields, music, cellphones, operating systems AND music portable devices is really too much to ask and too much to wish for.
