Thanks for the replies!
I do want the IPS this time around. I had overlooked the X200 at first because it didn't ship with IPS and I am not a particular fan of the "speed stripes" antenna design above the screen, but it's starting to make some sense to get that with an IPS and the mediocre resolution for $500 rather than getting an X220 with a mediocre resolution for $800. I might miss the flexibility of having the digital video port on the X220 but I don't need it right now.
Can anyone confirm if either or both of the X200 and X220 have the soft rubbery lid finish like my X31 and T60p? Kind of hard to google this detail though looks like the X220 does.
The UX31A is the model I was vaguely recalling after seeing it discussed elsewhere, thanks for naming it! It looks nice but as a recent model starting at around $1000 it's looking unlikely I'd be able to get one for $800. It also looks like only the 1920x1080 model is IPS and I'm thinking that in a 13" I'd rather 1600x900. From numbers it doesn't seem like much but that 100-130 vertical pixels over the 768 or 800 resolutions might be nice. The Samsungs along the line of an NP900X3C might do the job, but I'd have to play with them first, plus there's still the price issue.
Has there ever been a 13.3" Thinkpad with an IPS screen, or has anyone ever transplanted other manufacturers' IPS screens into an X300/X301 or similar? I wouldn't mind getting something a little larger than the 12" without going to a 14", but I want the IPS as well.
Still a bummer I can't get a 12-13" 1400x1050 IPS Thinkpad with a cherry on top!
pianowizard - I actually saw one of the CF-Y*s in person, not sure if it was the 5 or 7 - my boss in 2007/2008 owned one. It was impressive, but I recall not being crazy about the keyboard, and the touchpad always struck me as a little... unusual

. Certainly a laptop of its own kind!
