never even heard of a dvorak and not sure if I would want to use one, they look really hard to learn to useI'm tempted to go for a us keyboard and that would take some getting used to with the smaller enter key and @ changed around, but could never use that o.o
Its supposedly more efficient seeing as qwerty was invented to stop typewriter jams. I'm learning it now, its not much more difficult than qwerty.
Thinking about it I need a keyboard with multimedia buttons specifically mute and volume controls so I think my only real choice is the Zowie.
