dasKeyboard ultimate. MC cherry Blues with blank keys.
I used to wear out keyboard quickly, and have had this bastard for 2 years and still going strong. I absolutely love it, but it might be pricey for some and the noise might irritate people (I love the noise).
Mechanical keyboards don't make you faster/better typist, but they are more fun to type on.
The only good ergonomic keyboards I've heard that work are those split ones that the keys curve up around the hands and those vertical ones. The wrist never needs to move.
Most problems caused my keyboard and mouse usage is placement, not the mouse/keyboard. I used to have wrist problem until I learned to type with my wrists elevated and my arms at 90degrees.
Blackwell! Ah... you might want to get rid of that wristwrest. Most problems with the wrist is caused by stress on and within it. There has been many studies that have proved wristwrests to cause more pain because you're applying pressure on the carpal tunnel.
What I recommend:
If you have the money and you slave away at your keyboard for almost 4 hours a day, invest in a mechanical keyboard.
- IBM Model M run about $50-60 on ebay. They use a PS2 plug, so you might need to get a PS2 to USB adapter. But, they last a lifetime.
- dasKeyboard. $100-130 There's regular and silent. The silent are quieter and you can google "o-ring mod" and that will make them deathly quiet. If your typing alone, go for the regular for sure. Regular vs Ultimate, is blank keycaps. I recommend if you can already touchtype to get the blanks.
- Filco/ducky. $140+. Not better than a das, but are more standard and have a lot more options.
If you're going to spend anywhere over $70, get a mechanical. Just avoid "gamer" keyboards.
