Migrating = to windows? never left. Won't start down that dark path of discussion = though, I've said my peace. Let's just say I won't be buying any $300 = thunderbolt USB hubs anytime soon.

However, one sincere question: = does thunderbolt have any advantages over USB 3.0?

Thunderbolt vs. USB = 3:
