Someone in another thread mentioned IPS screens. Now I'm curious. What is IPS? What do the letters stand for? What does IPS give me? Is IPS something that only Lenovo has? Is it only on the T series?

Acceptable picture quality getting closer to CRT monitors

Yes (speaking of notebook displays)

Currently yes. There were R (R51 was the latest) and A (A31 I guess) models using this panels in the past as well.

Interesting. Thanks for the Wikipedia link. I see there are several varieties of IPS: the original IPS, S-IPS, AS-IPS, and A-TW-IPS. Which does Lenovo deliver?

I think it is S-IPS. You can try to find detailed information using LCD panel part number from
ThinkWiki table

How can I tell whether a particular model comes with an IPS display then? Are the FlexView displays IPS?

Yes, Flexview displays are IPS. You get these only in the 15" versions, though.

Hmm, that's interesting that the T60's Flexview screen is S-IPS... I didn't know that.
I read that the T60's screen is highly improved over the T42's in terms of blurriness (and I haven't found blurriness to be a problem on my T60), so I wonder... did the T42 have a regular IPS screen (as opposed to S-IPS), or were the parts used the same (and the improvements achieved some other way)?
