After some incipient carpal tunnel, I splurged on a Kinesis Advantage 2 keyboard. I loved it so much, I bought a second one to take with me to Vietnam. That way I didn't have to lug it back and forth.

Yes, it did take awhile to get used to the layout. After daily, 20-minute TIPP10 practice for a week, up to speed with the new layout. Well, my speed. I still have to peek at {}<>[]. I can switch back and forth between the Kinesis and my laptop keyboard with no issues. Their feel is so different, that my muscle memory isn't confused.

It is very loud, which is mostly noticeable while taking notes on a video call. Two modifications helped some.

I bought some little silicone o-rings. They really cut down on the noise. It took a day or two to get used to the slightly softer feel, but it's so much quieter that I don't mind. I'd definitely recommend them to anyone who is unhappy with the sound.

Second, my friend had some mass loaded vinyl(MLV) from a sound proofing project. I cracked open the case, cut it to shape, and glued it in. I worried that foam might break down over time and get in the keys. The MLV also helped a good bit. It eliminated the hollow, twang sound when the keys bounced back.

My last modification was to stick an Apple Magic Trackpad in the middle. I just used a loop of tape. With it in place, I can even set the keyboard in my lap when sitting on the sofa.

I'd love to hear about your setup, especially if you use the Kinesis Advantage 360 Pro Split!
