Trackpoint is not tunable, can't lock function keys, easy to miss cursor keys.
You can't lock function keys, always have to use Fn key.
There is no way to adjust trackpoint setting separatley from mouse, like it was in usb keyboards with trackpoin(at least old ones.
Cursor keys are small and flat which makes them easy to miss. Cursor keys on older keyboards had same size, but they had convex shape and each one of the had bumps like on F and J keys, with made them impossible to miss.
I have one request for keyboard function.
At Windows, "Fn Lock" is required for one push F1 to F12 like lenovo compact keyboard.
This keyboard require two push as Fn key and F1-F12.
