Ah, it is noticeably different, and clumsier, but I don't use it! I have used Thinkpads for decades and love the trackpoint, am happy to be back to being able to almost entirely ignore the trackpad.

In my limited use I'd say the surface is a little less pleasantly tactile compared to the MBP, there is slightly more latency in initial response, and it is slightly more jerky when scrolling. The latter two feel mostly like driver issues. I am aware of people doing work on the drivers to get it a little closer to the feel of the MBP, but don't follow it too closely.

Hope that helps.
