For those who type on German keyboards or in German, there are a number of layouts that have evolved around the Neo 2 layout [1]. The main driving force is ergonomics, but since not everyone works the same way, many variants have emerged (and still do) [2]. Interesting is the craftsmanship, including customized programs to optimize the layouts [3].
I always changed to ANSI layout, independent of the layout of the actual keys. Now I carry a HHKB with me, and connect through BT to whatever computer I want to work on. No matter what human language I write in (I do some) I prefer using accidents like tildes and umlauts with modifier keys.
