Nice! The only thing I'm kinda missing is the type of the pointing device. But, since it looks like Lenovo is currently the only one with the trackpoint and there is nothing else out there (is that right?), it's not too hard to just filter by brand and then look at pictures.
Perhaps, separate "Lenovo" and "Lenovo/Thinkpad" because they are really quite different machines?
14" and larger Dell Latitudes are available with a pointing stick. Most 12" and larger HP elitebooks are too, but they only have two buttons. Some Toshiba Tecra R and Z series have two-button pointing sticks. A very few ASUSPRO machines have three-button sticks, but none are available in America.
