I guess everyone is different. For me, laptops especially the MacBook help. The mouse was the problem for me, and when I started getting RSI over 20 years ago, I discovered that when I used a pen-type mouse, everything cleared away. It was because I was using the mouse at the side of the keyboard and that was causing my wrist to twist, which ended up aggravating the nerve in the wrist that ran up and down my arm. I ended up typing on an ergonomic keyboard, with my mouse in the middle. Whenever I need my mouse, I would push away my keyboard and use the mouse where the mouse is right in the center with my hand slightly askew at a similar angle to where I write with a pencil. This prevented the nerve from being twisted, and my RSI has largely gone away since then. The MacBook keyboard with the mousepad also in the middle seems to work well for me as well. The main thing is ensuring I don't twist my hand away away from my body that causes the nerve to get compressed.
