For what it's worth, one of the things I did with my interview process was to make all the coding involve an actual computer. I gave the interviewee their choice of editor, and was happy to let them use their own computer.

My theory was that in an interview I wanted to see people at their best. I wasn't hiring them to code on whiteboards or learn how to use new text editors; I was hiring them to spend a lot of time coding in an environment they liked.
