In general I would agree with corkyg. It's probably a matter of getting used to for most people. I was recently posed with a similar issue and held off for 1920x1200 and am glad. The extra pixels are certainly no issue regarding movie watching, but having them is to me at least a noticeable advantage when doing large projects. I bought the monitor (ASUS Pro Art PA246Q) cause I felt I needed the real estate and have not been disappointed.
Addendum:
Oh yes, one of the things I noted during monitor shopping was that a 23" 1920x1080 had effectively the same physical height dimension for LCD screen size as my old 1280x1024 resolution 18.1" DELL UltraSharp 1800FP (close enough for government work). So (unless Im wrong) it seemed that when watching a 4:3 aspect movie size wise would be the same. The PIX is no doubt better quality, but it seemed weird that there would be negligible difference in size presentation (assuming 4:3) going from 18.1" to 23". Sort of was a show stopper for me regarding 1080. (I would say that a third of movies are 4:3 as I get lots of old ones from the public library which Ive never seen). On the ASUS PA246Q, the 4:3 movies use the complete height (ie, 1200 pixels) of the monitor. As the aspect ratio is maintained, I therefore end up with a significantly (ie, noticeable) larger overall movie presentation then a 24" 1920x1080 panel.
