I type since 10 years on the QWERTZ layout, this was/is ok for me too.
But this layout isn't "really" ideal for everybody whose native language
is not english.. you know, but this is also true for the Colemak layout.
Specially for germans the NordTast
layout may be an alternative.
Why Colemak, hmm we all creature of habit. The fact that the letters
"qwahzxycvbm,." are unchanged on the Colemak layout is personally
an advantage for me.. still i will feel how it is in another Church ;-)
