We could have a good discussion on ergonomics. It's been over twenty years since I slipped a mention of it into each of my computer classes. It's been almost as long since I remember discussion of it on these forums.

I am very interested in being updated on the carpal tunnel issue, so thanks. My doctor was quite sure when I came in after writing parts for symphony orchestra for one of my concerts. That was a ton of close mouse work in a concentrated time. As a result, I'm pretty good now switching off with my left hand. I also tried everything: trackball, Wacom tablet, different shaped mice, wrist pads etc. Now, I'm back to just using a regular Razer wired laser mouse.

ps to the OP, swingbabymix: I assume you are considering what is called an Apple Magic Trackpad, the device in your picture. "Apple control board" is something else entirely. I've read that the newest Apple Magic Trackpad works in Windows 10 but I assume some operations involving multi-finger swipe, touch and pressure might not be supported unless you connect it to an Apple machine. Even then, I saw a mention of third-party software that will emulate those actions. But as a straight mouse substitute for BIAB, it should work.
