In the TN market, there's been a HUGE push to 1920x1080 in the 23-27" range. Probably sharing panels with TVs and the like, plus catering to a standard TV resolution in the most popular panel type. I found 1920x1200 at 24" bad enough with the number of pixels per inch, but I'm a fan of high PPI. I can't imagine how pixelated 1080 would be at 25" at average computing distances 😛
1920x1200 TN panels seem to be going the way of the dodo bird, however. They're still popular in the PVA or IPS markets since those usually don't cater to the average consumer, but expect to shell out $300 at least if you can find a sale. A good IPS panel not on a sale can run $500 or more easily.
If you do drop down to 1920x1080, you're going to find tons more options, including some lower end 24"/25" monitors at sub $150 prices on sale. 1920x1200 is just getting rare for consumer level LCDs. Hell, Tiger Direct only carries two 1920x1200 monitors, but carries 125 1920x1080. If you're keen on saving money, dropping to a smaller screen at 1680x1050 or to a 24/25" at 1920x1080 might be your only bet.
Laptops are also following suit. Dell's even starting labeling their resolutions as 900p, or 1000p, or the like instead of actually listing the normal resolution. Really annoying.
