I fucked my wrists by spending 8+ hours a day on a laptop from age 12 to 22. I have one of those at home, and one at work. They are really good. I went from being able to type 25 hours on a regular keyboard to 50 hours a week with minimal pain on this one.

The sculpt has empty space in the middle (above the space bars), I always liked the thinkpad clit mouse - so I hacked a small trackball in the middle of the keyboard.

(This one: https://www.amazon.com/dp/B00810ROQ4)

The trackball buttons are not really accessible, but the keyboard has two space bars, so I rewired the left one to be left mouse click.

The warranty is definitely void, but it was worth it.
