Two questions about thunderbolt display 1. Why is everyone buying them? Thunderbolt costs 999 dollars. You can buy HDTV with 40-46 inch screen with that money? I am just trying to understand why. 2. I have a 2010 MBA, but it doesn't have thunderbolt port. Will it be compatible? Should I get old cinema display with mini display port instead? Please give me some advice and I appreciate your comments. Thanks.
