Just because average joe is ignorant to the details does not magically transform PVA into a premium panel. My mom might not be able to tell the difference between wine in a box and a $200 bottle, but that doesn't make it a box of premium wine.
Value is specific to an individual. I won't own a wide color gamut display (yet), another CCFL display, a TN/PVA display, or a display with awful amounts of input lag. There are other folks out there that would have similar issues to a subset of this list, and that makes the 2408 a poor choice for them. If they have a different set of needs then they would possibly have a different opinion.
On the flipside, the speakers in the ACD are perfect for what they are, the webcam is a nice bonus, and the charging connectivity to my MBP is awesome.
