Fellowes Split Design Ergonomic Keyboard
- Split spacebar: Nice!
- Condensed arrow keys: bad! (try play pacman with it.)
- The Alt key is between Z and X. This means, your thumb needs to curl in a lot. On Microsoft Natural Keyboard and Microsoft Natural Ergonomic Keyboard 4000 the Alt is between X and C.
Majority of reviews on amazon are positive, many prefer it over Microsoft ones. The keys are the type that requires more pressure.
