Are you willing to work on other devices besides desktops and laptops?

I get questions from time to time about problems with other devices like game consoles, PDA’s etc. I’ve done a bit of trouble shooting on consoles and have opened up older generations of consoles to clean the dust out of them. I haven’t tried working on the current gen consoles though. What do you think? Do you think it would be worth it to get some training (even some trial and error DIY at home training on my own consoles) on fixing consoles? I’m sure I’d have to make sure the warranty was already expired on the console before I opened it, but besides that, I can’t decide if I should branch out into game consoles or not.
