I made the switch for a solid two months. I wanted to love it and wasn't going to let the steep learning curve or learning a new layout deter me from my long term goals, even if it meant I was typing at 15wpm and many mistakes for a few weeks. At the end of it all, I can definitely say that Dvorak is much faster/easier to learn/less stressful than QWERTY given the same time. It is a better layout than QWERTY for keyboards plain and simple.
The world runs on QWERTY. You don't realize how prominent it is until you make the switch. I knew going in that there was going to be some compatibility issues since I was using a software remap. But I didn't actually know:
Use a different computer at work? Good luck typing at 1/4th of your original speed with insane mistakes.
Got your keyboard set to Dvorak on Starcraft and think its going to work great? Nope, half the game uses raw input and conflicts.
Type on a smartphone converted to Dvorak? Autocorrect is useless because all the vowels are so close to each other.
Want to play a stupid little flash game that uses WASD? You need a macro for that.
Copy paste? You need a macro for that.
Ctrl + Save? You need a macro for that.
Ctrl + Anything? Might as well macro your entire board while we are here.
Some of these things would be fixed with an actual hardware Dvorak board, but it doesn't matter for the majority. I did learn quite a bit on with that experience though. With all the macros I made and wanted to convert back into QWERTY, I made capslock my dedicated macro-modifier. As well I realized how my FPS playing really strengthened my QWERTY keyboard skills on everything except the farthest right keys. I mapped into a OKL: setup instead of WASD and now I can type one handed at around 40wpm and relatively few errors. Great for when you are feeling lazy.
Honestly, I don't want to discourage you from trying it because your experience might be different. I would recommend against getting something like a highend mechanical wired only in Dvorak because you might find its not for you. If you want to jump into it
I recommend this site because it helped me so much. If you use Chrome, prepare for your first annoyance of many.
