Oh.. then I'm not sure what we're doing differently, or what the difference is in hardware, but my arms/hands are straight from elbow to fingertip when I rest on 'home row' 'adsf'/'jkl;' - if I change to 'wefv' it's a significant contortion, if that's what it looks/feels like for some people using 'asdf' then I understand the problem and am not surprised they don't put up with it!
If I stick my elbow way out I can make 'wefv' as natural to me as 'asdf'. So I suppose either my elbows are more tucked in, or my keyboard's wider ('dfgh' for example contorts the other way, and analgously to 'wefv', 'rthn', or better but less analogously 'erth', is more comfortable there).
