I think you're overselling the old screens. They were bad TN screens with a crappy resolution (1024x768, 1280x800). At least the x220 and x230 have a very nice IPS screen, even if it's still with the crappy resolution. Unless you mean the SXGA+ X61 with the gorgeous 1400x1050 IPS screen with just the right aspect ratio. But those only existed officially in the crappy tablet form factor. It's possible to mod one of them to a normal X61, but it's highly non-trivial and takes a lot of time and money.
