Wow... USB 3.0 is awesome! Wondering how much better Thunderbolt is now.

I've been keeping track of the Time Machine backup my new USB 3.0 is making and noticed it's backing up 1GB every 8 seconds. It's kinda blowing my mind right now and actually making me want a Thunderbolt drive.

Has anyone used TB for their setups? I was looking at one today and considered it but I didn't know if it was overkill for stuff I planned to do like basic backups, gaming off of external drive, and possibly editing 1080p videos for Youtube (nothing major)...

Is it worth the extra price?
