It’s true you can use a mac with a broken (partially functional) trackpad — I did for a couple of years and it wasn’t a noticeable impairment...but I’ve been an Emacs user since the 70s so am keyboard-by-default already.
But I can’t say the Mac is the best: Windows, back in the Gates days, had keyboard commands for almost everything at his insistence (some of the PMs weren’t enthusiastic but couldn’t go against him of course). I’m not a windows fan (prefer the Mac’s direct manipulation approach to the subject-verb-object model at the foundation of Windows) but I really respected and appreciated that commitment by MS.
