But Thinkpad keyboards *are* ergonomic. ;-) You just need to figure out how ton
keep your wrist straight and let your arm follow your hand while typing.

Trackpoints aren't ergonomic, though. Those things are terrible for the tendons
on the back of your hand because of how much pressure you need to put into them.
I still use mine heavily though, with an aggressive sensitivity setting.


/etc/udev/rules.d/66-trackpoint-config.rules:
ACTION=="add", SUBSYSTEM=="serio", WAIT_FOR="protocol", ATTR{protocol}=="TPPS/2", WAIT_FOR="sensitivity", ATTR{sensitivity}="255"
ACTION=="add", SUBSYSTEM=="hid", DRIVER=="lenovo_tpkbd", ATTR{sensitivity}="255"

/etc/X11/xorg.conf.d/50-trackpoint-acceleration.conf:
Section "InputClass"
        Identifier "trackpoint"
        MatchProduct "TPPS/2 IBM TrackPoint"
        Option "AccelerationProfile"  "2"
        Option "AccelerationNumerator" "25"
        Option "AccelerationDenominator" "10"
EndSection

Section "InputClass"
        Identifier "trackpoint-usb"
        MatchProduct "Lite-On Technology Corp. ThinkPad USB Keyboard with
        TrackPoint"
        Option "AccelerationProfile"  "2"
        Option "AccelerationNumerator" "25"
        Option "AccelerationDenominator" "10"
EndSection
