I really hope there is a matte option. I'm not holding out too much hope though.
If there's no matte option and no height adjustment there really is no reason to get a 27" ACD over a Dell U2711, especially because Dell guarantees zero dead pixels for three years.
My only other concern is that the dot pitch is too small for text/office work.
Forget Dell. Got a 3008 - after 6 months 10 or more dead pixels. Was exchanged. Replacement monitor worked 3 hours, than the left half of it was dead. Can't return the damn thing (IT only allows exchanging to the same model) so I am buying from my budget if needed a Mac Display. Never had problems with those. Hoped for the 27', maybe Tuesday...
