Discovered this keyboard “ThinkPad USB Keyboard with TrackPoint” ThinkPad keyboard
It's a external USB keyboard, with embedded Pointing Stick (a red button between G and H). Compact, laptop style shallow keys.
I don't recommend it. Because laptop style keyboard is the fastest way to get RSI. If you are going to get a external keyboard, get a full-sized one.
My recommendations are:
- If you want split keyboard, see: How to Chose Ergonomic Keyboards
- If you want straight keyboard, try Logitech G710+ Mechanical Keyboard and Keyboards without Numeric Keypad
All these have mechanical keys. (but check the page for detail).
Some people like the ThinkPad's Pointing Stick. I didn't like it. Too slow.
thx to Aenon Sun (孙锡麟).
