You should take a look at this extensive thread (33 pages and counting) - there you can find lot of information about that display. All in all it seems to be excellent LCD monitor in terms of its color gamut, display quality etc., but it also has some rather frustrating issues (especially if you're in Europe). On the last few pages of that thread you can find more info on that - it seems that this display emits quite loud high pitched noise, reported by lot of european users. Recently NEC acknowleded this and said to have some solution, but we'll have to see about that.
Anyway, if you're in Europe I think it's best to delay purchase and wait for some of the issues to be solved (or wait for nexr revision or something like that).
