IPS panels in the 21" size are pretty cheap at this point, and as I recall people noticed the switch to cheaper screens with the G5 era imacs. G4's used IPS displays. G5s went to TN at larger display sizes. I'm going to see what I can find on those cpus, as that it seems unlikely to me that they would use the same ones as the Air. With the old i3 models a few years ago, they used cpus that were a little over $100.
