I've decided to try the Magic Trackpad 2 and wanted to ask others for their experience switching over. Did it take long before your arm adapted to using it? If so how long. My arm is fatiguing quickly using this.
Trackpads give me repetitive strain injury. That's why I don't have a trackpad for my iMac, and one reason I prefer to use my iMac over my MacBook at home.
I much prefer a trackpad. I've been using the Magic Trackpad since 2010, when it was a free thrown in when I bought my 2010 MacPro. Today I use it with my Mac mini. Note that I also have a Logitech MX Master 3 mouse, but I use that mostly with my work Windows laptop and only occasionally with the Mac. I find I have much less fatigue with the trackpad, as my arm stays put resting on the desk. Good luck with it.
