I was in the market for a new external HD so i went over to the local Best Buy to see the selection. I decided to buy the WD My Book Essential since it has a USB 3.0 connection so it would be "future proof". I currently have a Macbook Pro Unibody 13" 2.26ghz, so i wont be upgrading anytime in the very near future, but when will Apple start adopting USB 3.0? Or is there a reason they will not at all or anytime soon?
