Many years, many machines
Yup - I've been using Mac keyboards and mice on Wintel machines since the current mice (post hockey pucks) came out.
It's kind of funny - on some machines, they work flawlessly. On others, you can't even get it to accept your typed letters without a driver. But, I guess that's why it's called "plug 'n pray". 🙂
So, yes, use your Mac input devices. Your joints will thank you!
