 I bought a Dell Latitude E5450 about a year ago. On paper it combined

-stick][pointing-stick](my fingers seem to be incompatible with touchpads) and
-an OK price. The only alternatives would have been HP, but they don't have a
-middle button for their pointstick which is vital for scrolling, and Lenovo,
-but at the time they only had Thinkpads without physical trackpoint
-buttons(horrible, but I guess a lot of people complained, because now they all
-have physical buttons again - too late for me).
