Every monitor I had before this present Z35 has been glossy. No problem with fingerprints etc since there is absolutely no reason to touch the screen except when cleaning.
I did buy a Dell Ultrasharp which had a matt screen. Used for one day, absolutely hated it and gave to wife.
Finally bought the Z35 which is semi-glossy. Had to calibrate like crazy before the colors came close to my previous monitor, the Acer F22, which had absolutely beautiful colors. The F22 did reflect like crazy though but got used to it so didn't really notice.
