The premise was accessing Google Music from an iOS device...apparently a phone at that. It wasn't seamless. Duh. Why would you do that? If there happens to be some track you have to have and iTunes ain't got it, OK, but I'd be willing to put up with a little hassle in that instance.
Might have been easier on a Mac, since one complaint was that Safari brought up the service as a desktop page.
But really it is shortsighted of Google not to accomodate the iOS user who just must get to a track, that isn't available on iTunes, and must do it while mobile from his iPhone. How dare they.
BTW, I'm a Zune user, and I have on occaision had to resort to getting a track from Amazon or iTunes, because of who offered it, but I did it from my PC at home and it was pretty painless. Even have Zune looking in the directories favored by those other services, so I don't even need to do anything but click the buy button. (Don't tell anyone, but I listen to my Beatles anthology on my Windows Phone)
