There is usually one primary task on one, but it is highly beneficial to have access to the other (e.g. writing some documentation related to the primary task).
I have been trying to think of ways to improve the experience.
The only reasonable solution that I can think of is to use a KVM to be able to use one magic keyboard and one magic trackpad, to drive both macBook pro.
However, I really love the built-in trackpad, and I've read that the external trackpad is less good. In addition, it is wireless, so I'm not entirely sure if that would even work with a KVM, and even if it does, I would expect way more issues that if it were wired.
In an ideal world, I guess there would be a way to buy the built-in keyboard/trackpad combination, wired.
Any random thoughts or experience sharing much appreciated, thanks!
