I'm a fan of the Microsoft Sculpt keyboard. Mouse is nice, too, but the keyboard is great. Quiet, responsive, wireless.<p>I had an ergonomics issue that Microsoft split keyboards resolve.
Mouse: Microsoft Wheel Mouse Optical 1.1a USB on Mac and PC<p>Keyboard: Microsoft Comfort Curve 2000 on PC, Magic Keyboard (2. Generation) on Mac<p>I really like the MS Wheel Mouse Optical, unfortunately it is no longer produced. I tried different mice, but I think I like it that much, because it has lower DPI (400 DPI) than an average mouse (about 1000 DPI). Nowadays it is difficult to get a mouse with 400 DPI.
HHKB2 with a CRT LaserTRAC trackball.<p>Got another Ergodox after hankering to try it again after selling my first after a couple months, waiting until I have a little less work to transition over to it as my WPM drops to about 10 while I'm learning.
I use a Logitech Wave at the office. It's not a fully ergonomic keyboard, but has a slight, well, wave. It's comfortable to use all day, but isn't too drastically different to affect my typing style on a laptop keyboard when I get home.
Keyboard: MasterKeys Pro S Mechanical Keyboard Tenkeyless<p>Mouse: LOGITECH TrackMan Wheel Optical USB/PS2<p>I have at least 3 TrackMan Wheel's, one I always bring to use at the current place of work.
MX Master Wireless + Original Apple Wireless kb (non-shallow keys)<p>I know I should probably check out mechanical keyboards, but I'm just too damn used to the MacBook keys.
