Why would you use a touchpad if you have a trackpoint?
Get used to the trackpoint: less fatigue, faster and more exact control of the cursor and more ergonomic since your fingers pretty much stay on the homerow = less wrist movement (unless you use your thumb).
I'm not saying I would. I prefer the trackpoint. But they should provide a decent trackpad or get rid of it altogether. I don't need both. This would make more space for palmrest, which is too small in x220.
