Fair enough, but when I look at pictures of peoples' builds it is almost always a square keyboard with fancy backlighting.
I'm personally a fan of the MS ergos with the wrist wrests and have mixed feelings about how that design doesn't seem to be getting replicated anywhere
I would guess there's a patent involved preventing another company from using it. I would definitely have bought an MS 3000/Sculpt with mechanical switches before I built my own ergodox. My problem was that I wore out my sculpt in like 14 months. Half of the space bar stopped working. I'm actually a little surprised Microsoft hasn't released one with mechanical switches.
This is where I disagree. I had severe hand and arm tendon pain for years, and finally dove into ergonomic mechanical keyboard options. It solved my issues, and I no longer feel the pain after typing all day.
I easily spend $350+ for a keyboard, and it's a very practical, life-changing decision, which involves a non-rectangular, non-RGB keyboard.
