I am shocked at iTunes Match and will be gobbling that up. $25 for them to unlock my entire CD collection (hundreds and hundreds of discs) on the iTunes store and push it to all my devices is not only a great deal, but also waaaay easier than uploading terabytes of data to Google.
Looks like my huge ripped CD collection, file server, and syncing over the wire is a thing of the past. I am quite happy with this.
Edit: On a side note, how can this possibly NOT be abused? It essentially runs on the honor system, you telling iTunes "yeah, I own this song, unlock on my iPhone please."
I am very curious how the "checking" tool will work. What stops people from making dummy files?
