I've been typing dvorak primarily for about 20 years, also since I was in high school, and I highly recommend it. I agree that switching is a pain in the ass. It will make you essentially unable to type for about 2-4 weeks. Ctrl-C/V/X is a valid concern. I fixed it by mapping mouse buttons to copy/paste, and also getting an Advantage2 Kinesis into which I've programming custom keybinding for Undo/Redo/Copy/Cut/Paste.…
I recommend using this, in my mind a way bigger improvement than just moving to dvorak itself. It's like having vim navigation everywhere, but better.

Pretty sure my WPM is something like < 20 wpm in Querty (70 in dvorak). I look like a complete beginner whenever I'm on someone elses machine. Not really sure how others keep the dual fluency.
