New Mac mini, dual 24" or single 27" monitor? Thoughts?

I've used a U2711 for a year, but finally had enough of its anti glare coating's shimmering, and when I had an opportunity I sold mine and got Thunderbolt Cinema display. This is very glossy, but I use it in a semi lit room so no problems. Clarity is much better, plus the TB connection makes good sense in my environment.
