Rather than the hand sweeping all the way over to the right to reach the mouse, it just twists a little towards the trackpad. The palms never really leave their rests.
I don’t use it like this a lot, but when I do I enjoy it.
That said, I love the Mac trackpad and it has great ergonomic potential, I just personally have to use it with a split keyboard with the halves on either side of the laptop. That way the motion of moving from trackpad to keyboard and back is a bend at the elbow, while the wrist stays straight.
A few months ago I have discovered the joys of using a trackball and I think a great setup would be to fit the that between the halves of a split keyboard. I suppose a Kinesis Freestyle or similar could accommodate that.
That being said, even though I absolutely love the mbp trackpad and find the keyboard ok-ish (I have an older, 2013 model), I don't like using it with an external screen. It feels somehow off.
I'm pretty sure I saw something like that from lenovo. I can't find it anymore, all I got is this:
