Are there any manufacturers who ship laptops with Ubuntu as the default OS and also have a pointing stick (trackpoint)? I found several companies like System76 who have great-looking laptops, but none have the trackpoint. I have been a Thinkpad user for 10 years now and can't imagine not having a trackpoint.
Haven't used it myself but http://www.emperorlinux.com/mfgr/lenovo/toucan/ is the one I had found long time ago. Looking at the price, you may be better off buying a thinkpad with free dos and installing ubuntu yourself.
