x200s have an IPS screen, I think. It's the x201 with the crappy screen (which I'm writing this on...). You can switch out for a nicer panel if you're willing to put the effort in, but if you're looking to buy, may as well look for other models.
There's no other model that surpasses an X201 though :(. I'd pay a lot of money to get an X201 with a Broadwell chip and a 1920x1200 screen. That's all I ask.
I have an X61T with the SVGA+ AFFS-IPS screen (1400x1050). The colors are the best I've ever seen on a screen, and at 12 inches the PPI is the same as my smartphone. Laypeople are genuinely impressed by it and will comment. The "retina" displays on Apple tablets are better, but people aren't used to seeing that kind of quality on a 2007-era laptop.
No, the X200s only came with TN screens. I actually swapped my 1400x900 TN screen for a 1280x800 AFFS. (In order to do this, you have to swap the entire screen assembly for a X200 one, _then_ swap out the standard panel for a HV121WX4-120. You have to do this because the 1400x screen uses an LED backlight.)
