Since iPod has 74% of the market
http://www.afterdawn.com/news/archive/19294.cfm and the closest competitor (Sandisk 7%, Microsoft 1.1%)..... At least to me it would seem that other devices are not continuing to "dominate a good chunk of the market".....
I know if I had a company that had 74% market share, I would be quite happy and would not worry so much about my supposed "propitiatory policies"...
I do think the internet appliance is the wave of the future. Apple is a company that could in fact be the game changer.... but the fun thing is we don't know, and ANYTHING can happen. It will be interesting in 5 years to reflect on all this
