16:10 isnt going anywhere, we are seeing a rennesaince of affordable but good 16:10 aspect ratio monitors in the mid-end market.
16:9 is not a good pc resolution, and while the above gif/screenshot of 16:9 vs 16:10 looks favourable towards 16:9, you have to remember that by going from 16:10 to 16:9 on 1920 wide panels, you are sacrificing vertical resolution, not gaining horizontal resolution. The only 16:9 panel in the 22-24" size I really liked was the Sony with 2048x1152, but alas, they're hard to find now.
That being said, if I had to choose between a 16:9 27" with 2560x1440 res, and a 16:10 24" with 1920x1200, my choice would be the 27", but only because of the higher total resolution. My preferred choice of monitor with 2560 horiz resolution would be the 30" 16:10 with 2560x1600.
Also, remember that a quality monitor lasts for years, I have a LG 24" (1920x1200, P-MVA) that was bought new in 2007, and I also have two HP L2335 (23" 1920x1200, IPS) that was produced in 2005. They're doing a great job still, and hold their own in image quality versus newer consumer monitors.
Monitors are one of the few things, including power supplies, cases and fans, that you really shouldnt skimp on. Consider that the monitor is your main interface along with keyboard/mouse, why would you want to ruin your eyes on a crappy monitor that only lasts 1-2 years anyways?
