So nearly all PC laptops in the past couple years have shipped with touchpads that lack physical buttons--the whole pad is a button.
Being used to Macs, I've encountered an issue with nearly every PC laptop from the last few years: resting your thumb on the bottom of the pad where the buttons used to be produces erratic behavior. The internet is filled with people experiencing the issue without finding a satisfactory resolution:
Some people manage to fix it in Linux (!!!):
Now, every Apply laptop I've ever used does not suffer from this problem; it correctly ignores the thumb when it is resting on the bottom part of the pad.
For those whose answer would be "just don't put your thumb on the pad, duh," you don't know what you're missing. It's an incredibly fast and precise way to position the cursor. The number of Mac users who use external mice because their trackpads seem too slow is very low, compared to PC users (anecdotally).
Does every PC laptop user adjust to their frustrating, defective touch pads or use an external mouse (defeating part of the point of a super-portable computer)?
I simply do not believe that after six years, there is no way to get this highly desirable behavior for PC laptops in 2016. There must be a way to fix this.
