iCloud Isn't The First Music Service, So How Does it Compare?

"Just as they teased in a press release last week, Apple finally took the wraps off its long-awaited "cloud services offering," iCloud. While Cupertino may act like theirs is the first such service to market, the reality is, as usual, something else entirely."

It certainly isn't the first, but is it the best? I'm sure Apple wants everyone to believe that but until you do a comparison like this article, it is pretty hard to judge. Obviously this is based on the information we have today, so there are some unknowns (Google Music Beta since it's by invitation only), but I'd say it does stack up pretty well so far, and if nothing else, is a great start. What are your thoughts?
