Being a macintosh user, I am glad to see them achieve such success with the ipod (I do graphics work), hope their computer business will benefit more from it (apart from my XB, I despise most microsoft products)
The itunes software is one of the most used programs on my computer,
If you picked apart the features on an individual basis (size, battery life, price), ipods may not be the top option, but as a whole package, they can't be beat, and are very cool to have to the point ipod is a household name...
