Thinkpads are pretty much the worst form factor for a laptop that doesn't transition into "toy" space.
Source: forced to use one daily. If I could get a Mac laptop running Linux but with the input smarts of the Apple trackpad and keyboard, I would in a heartbeat.
That shows that 1) people are different or 2) you are a fan of Apple hardware. It doesn't show that Thinkpads are bad. IMO they are light-years ahead of anything Apple sells.
My trackpad is automatically muted/unresponsive while I'm typing. I suggest you figure out how to get palm rejection to activate/work on your setup, and to look if a different Thinkpad series might better fit your body (ergonomics wise).
