No way, José.
From where I sit I have 5 Thinkpads set up within reach, and I have a few more in other rooms. They are by far my preferred laptop.
Most run Ubuntu as their default OS, most have the trackpad disabled because I usually use the trackpoint for everything, and on all of them I use middle-click to paste extensively.
Glad you're less clumsy than I am. :-)
The accidental pasting definitely kept happening to me, likely due to my bad habit of highlighting sections while to focus on them.
