Agreed, this keyboard is just awesome. I own a Thinkpad laptop and one of these keyboards at home and work. Perfect key sizes and not very loud. But if you do need that feeling of getting some work done or type up a stern email or two, go ahead and give your keystrokes some oomph. I'm always pleased with results :)
Seconded. The best keyboard I ever had belonged to a third generation IBM Thinkpad. When I saw the Thinkpad keyboard on amazon, I jumped on it. The trackpoint takes a bit of getting used to but it is really great for programming because your hands can remain in a single position and it'll help conserve energy and alleviate strain.
Apparently they removed the touchpad in this later model but improved the stickyness of the keys (some folk complained about the keys being mashy in the 1st generation.) I kind of would have liked a trackpad but the trackpoint does suffice, it's just really hard to get used to after years without one!
