See I'm the opposite, despite using primarily IBM / Lenovo laptops since it was first introduced (yes, am old) I never found it quicker or more accurate than a trackpad or mouse. The last few laptops I have had I now disable it and pull the rubber cap off.

That said the choice was always nice for people who liked it so I'm sure they will be disappointed by this decision. I wonder if Lenovo had some metrics behind this decision.
