I wish they made the trackpad smaller. They used to have (T420 and older) a smaller trackpad and a wonderful 7 row keyboard but they've since switched to a 6 row keyboard to have a bigger trackpad.
That means I'm stuck on the T420s for the foreseeable future.
I’ve got a T430. Had an X201 before that. It took a month to get used to it but I’ll be honest and say that I’m happy with it now. I dismantled it and wedged some paper under the trackpad though to stop it being pressed. That helps.
That means I'm stuck on the T420s for the foreseeable future.
