I love it, too. I hate that Lenovo no longer makes a ThinkPad with only that style pointer any longer. I always felt the trackpad was a big waste of space since I never use them.
Eh, as a T440s owner (granted, my first Thinkpad) I was a bit apprehensive about the lack of buttons but I actually exclusively use the Trackpoint now. The clickpad does click down like a button which is a little weird at first but you quickly get used to where the "buttons" are and then it just feels like normal. I use the middle click scroll a lot too. At least in Linux you can adjust the precise locations of the buttons yourself, I think in Windows you also get some options for configuring the button locations if the defaults don't feel right. Right now I feel like this is the best input system I've had on a laptop.
But getting rid of 7-row keyboard and clicky mouse buttons, so that a huge trackpad would fit? Not worth it.
