I love it so far, if it wasn't for many partial uploads with perfectly tagged music and same length as iTunes Store files that don't get matched for unknown reasons. This is really annoying but I'm sure it'll be fixed
iTunes Match is everything I've been dreaming of, even if it is buggy. The ability to have your one Music library on any (i)device and iTunes compatible computer with all your Star Ratings is what I paid for. It's a shame I had to pay for the privilege for something that I could have done through my NAS and router, but paying A$34.99 for the service, but that covers my space on their server and frees up my home network's bandwidth, so, go Apple.
Good thing I'm on an unlimited plan!
Oh and yeah, the bugs are bleeding obvious, but I've got a good swatter.
