For years, they were the only things I would use. I could never effectively use trackpads until I got my first MacBook which had the first one I actively liked rather than barely tolerated.

These days, I still have a Lenovo X200 for Linux and still use the pointer there although I'm generally happy with trackpads across the board. (Except on Windows apparently. I had to get a mouse for my 17" Alienware laptop because the trackpad still drove me crazy.)
