I have an X201 at work, and REALLY like the build, size, etc., so that for a personal laptop, I am thinking about going a similar route with the newer X220, even with the premium versus a more consumer-oriented option. But...there is also the T420. X220 Pro's Smaller IPS display (the premium display, according to the datasheet) T420 Pro's Larger screen, with 1600x900 resolution Integrated Optical Drive Those are the major differences that I am chewing on. The ~$150 premium for the X220 is a secondary difference, and I *think* other differences would not really effect my decision. But...thoughts or comments on either these items or others that may sway me one way or another?
