I've been in almost exactly this situation, although the issue was rather that I have a Linux tower without camera/microphone and a Windows laptop for playing some games or doing Microsoft / office stuff. Setting it up to anything resembling my real dev experience is probably a day or two of work, and the first time I used it for a job interview I probably seemed less than competent... I also have a work MacBook, but so far haven't used it for applying to other jobs, that would be kinda weird.
