A PC, several years old and a little banged up around the corners. (It's running Red Hat, although presumably he can't tell that from the back.) Last year in a fit of whimsy she gave it some tasteful decoration (http://arkhambazaar.com/bmz_cache/e/eee4119ffca11af6ab04dfdb34afe704.image.260x141.jpg), which probably tells Tony more about her as a person than about her tech savviness.

"Hey! Glad you could make it. Sorry, I've sort of taken over the table, let me clean all this crap up."
