If you're not tied to Apple, with my Air I use a Dell U2713HM -- an excellent display of the same size and without the annoying glass screen. Also plugs into the Thunderbolt port.
(These were bought through 3 different Amazon sellers [well, Amazon and 2 different marketplace sellers], so the likelihood of a bad batch was reduced.)

On the whole, I like the monitor. Non-glare screen, menu controls are pretty responsive. USB hub. But I wish it still had a legacy VGA port. If I ever have to reload some of my older machines, I'm going to be stuck since I won't be able to SSH/RDP in.
