A new feature to the iTunes Music Store is users' ability to purchase an iPod completely through iTunes. Why is this important? Several internet critics have speculated that the iTMS browser is the future of the internet: easy-to-use, simple, and graphically pleasing. This is one more step towards making iTMS a web browser.
Agreed. I've been thinking about this for some time. We need an iTunes Software Store, iTunes Amazon Store, iTunes eBay Store, and so on, and so on. This interface works because of the trick of the eye -- you don't believe you're online when you're in it. The metaphore of your iTunes library allows you to be in the sale without knowing it -- just click on an artist in your library and POOF, you can buy more just like that.
