I started using Dvorak out of curiosity more than anything. I've been using it for close to 4 years now, and I haven't noticed any speed gains.

It's inconvenient to use other peoples' computers; although, this is offset a bit by the amusement value of watching others try to use my machine.

The claims about ergonomics may be valid. My hands move a lot less when using Dvorak, but I can't speak as to whether the chances of RSI are reduced in any way by this, or if it provides any kind of relief.

Programming-wise, I haven't had any problems. The biggest concern there is that you might not be able to type for the first week or two.

Unless you have some significant reason to do so, I don't think I would recommend switching myself. I didn't see any significant gains, but your mileage may vary.
