Lenovo ThinkPad T450s 14" Touchscreen Ultrabook

I’m in IT. One of my clients has one of these lying around, except the i5 version (same body). I loved the form factor and size for its time, however, the trackpad on this model is TERRIBLE.

Hence the trackpoint

+1 for trackpoint.

This looks like exactly what I want for my wife for a work computer, but I can’t find a compatible battery for sale.

Am I bad at shopping, or is this a bad omen?
