(no notebook on the face of this earth has a IPS panel

)
Untrue. The Lenovo X220 has an IPS option. I own the tabletPC convertible version, the X220t that has this screen. It's very nice, but not really all that much better than the Macbook screens (which I also have a few of). IT's better no doubt, but just not really any better than the Apple screens, as these are very good, very bright, TN panels.
These screens are all so good now it's not an issue for the average user who isn't concerned about professional level color matching, and other professional uses. This wasn't the case just a year or two ago, but the TN panels keep getting better in terms of brightness, and perhaps contrast (not sure about the contrast, and there's of course, a number of technical issues that I, being an average user, am not aware of . Note: the viewing angles are much better on the IPS, but this is really only relevant for a tablet, and not for the average user IMHO).
I have a Macbook HD AG 17" with the better LG panel, and frankly this screen is better than any portable (maybe)

; better than the iPad or whatever. It's a TN panel, but it is very clear and the resolution really makes up for the other shortcomings (such as it not being of the lauded IPS variety).
note: Also, this particular IPS screen of the X220, has a very weird transient, ghosting anomaly, that the TN panels don't have.
I also have the 27" CD IPS that Apple makes. THis is actually the best screen that I own, but it's a bit heavy to carry to Starbucks daily.
