We just got our broadband connection a few weeks ago, and as I've been super busy, I haven't had a chance to try buying any music online yet, so I have some questions. 1) I'm mostly interested in jazz, so I'm hoping to discover which sites/services have the greatest selection. So far, I've only been to iTunes, which seems okay, but haven't spent much time with it. 2) I'm a Mac dude, so if something is inherently Mac unfriendly, that would be good to know. 3) When you buy an album, do you get e-copies of the packaging? On some of this stuff, I can't even tell who's playing on the record beyond the headliner. 4) For those of you who do this often, how much do you miss not having the actual physical product? It seems like it would be weird, but then I'm new to all of this.
