I started pulling out my Cherry MX keys only to find that the top row keys curved slightly differently than the bottom row keys after I pulled all of them out. :P I went ahead and tried to type on them a bit but found it to be slightly odd feeling (messed up key cap curvature and lack of index finger key bumps). Are there special Cherry MX key caps that are curved for DVORAK setup?
Here's the DVORAK layout for anyone is interested: http://en.wikipedia.org/wiki/File:KB_United_States_Dvorak.svg
