Aluminum iMac 20" display quality

[Hacker Scot]

I jumped too soon on the 20" aluminum iMac and didn't do enough  
reading in advance. The LCD has moved from the high-quality IPS in  
the previous 20" white iMac to a lower-quality TN display.

I immediately noticed that colors were washed out, bleached. The  
default color profile is terrible. Recalibrating helped quite a bit,  
but I can't seem to get it quite right. Then slowly  realized there  
was more to it than the profile. Fonts in general are not as smooth,  
and smaller fonts are downright fried looking. Then I noticed a  
brightness fade from top to bottom. The blue stripes in an iTunes  
window are dramatically bluer at the top of the window than at the  
bottom. Or Cmd-click messages in Mail.app from top to bottom and  
watch the blueness fade from top to bottom.

At first thought I had gotten a bum display, but started reading and  
finding messages like this:

Sounds like the 24" iMacs still use the IPS screen, so I'm tempted to  
return it and upgrade, even though I don't really want or need the  
extra size. I'm bummed about this. I love the 20" iMac form factor  
and feel like I've either got to live with the display downgrade or  
switch to a tower w/better screen or MBP.  Guess this was the main  
reason for the iMac price drop. Dang, Apple.

I'm no fan of this new keyboard, neither, but that's another story.   
Might get used to it.
