I also have 1920x1200 24 inch at home. I think I prefer it over 16:9 as I find vertical screen estate valuable, more so than horizontal, but not enough to go portrait orientation! Having said that, the laptop I ordered has a 1080 display...
Specifically for photos, 16:10 is closer than 16:9 is to the typical 3:2 of DSLR formats.
To put them in perspective of "wideness":
1.78 16:9 widescreen TV
1.50 3:2 typical DSLR
1.33 4:3 pre-widescreen displays, FourThirds format, compacts?
