but the thing is, that's a huge hassle. buying on a website, syncing in an app. what i really like about iTunes is how it's very tightly integrated with everything I use iTunes with/for. no webapp will be able to pull that off.

however, unless you mean explicitly browsing, in which case i might be inclined to agree because of the iTunes store links that only work in iTunes...that are useless if you don't have iTunes installed.
