Totally agree with the Professor!
The main gripe I've had always with iTunes is that you can't access all the musics from all your devices with your computer OFF. Now you can. It's the missing link.
Audiogalaxy does look good, granted, but the point made that you have to have the computer on is fundamentally flawed. It's no better than iTunes???
As for cloud. I think you are in the minority there. 'Clouds' are the way forward for so many technology companies. Everything is being geared to having your information (music/films/documents) stored remotely so you can access them wherever you are, with whatever electronic device you have with you.
Personally, I think that's pretty clever. I don't want to carry around storage discs, no matter how small/light they may be.
