I have a 27" iMac which has much higher resolution. However, at least for myself, I cannot tolerate this high resolution since it makes fonts tiny and web sized images relatively small (consider that large monitors are pushed back further than small monitor or laptops). Anyway, the solution has been to set my iMac to the resolution of the monitor you linked to and then all is well. I sometimes go back to the native resolution for Photoshop work. Also, using the native resolution of my iMac and increasing the fonts size only serves to screw up the text on some webpages where the words get pushed outside the frame.
As such my recommendation is to either go with a 24" monitor with that resolution or to get a 27" monitor which the higher resolution (if you have good eyes) to get the sharpest result. Personally, I wish Apple still made 24" iMacs (1900 x 1200) but they do not so my next computer may not be a iMac at all so I can use a monitor at its native resolution. Resolution combined with viewing distance, along with appropriate color gamut, are important things to consider when investing in a new monitor.
