In your article, you mentioned a lack of 22" monitors while also stating that higher resolutions show off monitor qualities. (And, many people are stating the desire to have 16:10 & 4:3 monitors in the showing.)
1. I must agree with the 4:3 & 16:10 monitor request, for I am yet another PC user that despises the push by manufacturers of the 16:9 standard on the PC markert just because that is what the TV market standardized on. (Reasons for these resolutions' superiority over 16:9 have been mentioned by others.)
2. Although I agree that higher resolutions allow feature qualities to be seen, there is also the GFX card's ability to game at that resolution without turning down game details. Since these monitors would most likely be used with a budget gaming machine, many games do not yet require the 1080p 16:9 resolution in width, and game quality settings can be increased if the GFX card does not have to push as many pixels, why not include a monitor similar to:

In this review? Was HDMI input a requirement? If so, I would ask why. (Most budget PC's will only use a single monitor that will be connected via DVI-I, not HDMI, since PC sound will be outputed through MB onboard onboard sound to separate speakers.)
I link this monitor in particular because my mate and I both use 2 of them in an extended desktop format on ~$750 gaming PCs. One is due for an upgrade to its 9800 GT 1GB, while the other has a 5770 1GB GFX card. The lower max resolution of 1680 x 1050 allows more game details to be ran since the machines don't push the extra 309,600 pixels. And, for office and productivity work, you only lose 30 vertical pixels from the 1080p "TV" standard.
3. Although TN panels do indeed not have the quality of more expensive panels, they get the job done. (Especially in a typical office environment... or for the needs of the typical budget gamer.)
4. The conclusion of needing to spend over $200 for a 23" monitor of "good, yet budget, pc quality" is slightly dubious.

(The new, 1080P, includes HDMI input model of the 22" ones we use. Just, for all Asus monitors, ignore the speakers.
