Hey Apple, hello? anyone there?!?
I've got my money in my hands, ready to purchase two displays today!
BUT,You know I felt the same way. I found two Dell monitors that looked good (I am a fan of Dell). Then I visited store that had all three on display and I brought my rMBP (mid 2012) with me along with a Thunderbolt cable. The salesman helped me try all three with my notebook. When I saw the TBD and the ease of connecting it, I no longer cared that it is 3 years old and not USB 3. I have had it for two months and remain very happy with my decision.
