I used Dvorak (and to an extent Colemak) back in college, and while Colemak was easier to learn, Dvorak had more advantages for my typing style and needs. I used it exclusively the last 2 years of college and really, really loved it.
The problem came when i took an IT job that required me to bounce around to different machines, or remote login, etc, and then i got all confused and looked rather incompetent. Sadly at the time I didn't really look into keyboards that could actually output Dvorak, as I was simply changed the input settings on my computer when I was learning it and on my main work computer. The frustration of swapping back and forth on the fly, daily, if not hourly pushed me back to Qwerty unfortunately. I still try to type Dvorak and Colemak here and there so I don't totally use it, but have become rather complacent.
So, I absolutely recommend it, but having a keyboard that can output dvorak will be your best friend, especially if you heavily use more than one computer.
