Another one of those awesome, annoying older brother types! What's great about Matt, however, is that Naoto can fanboy with him about various robot anime and sentai shows without feeling all embarrassed and self-conscious. She thinks he's an absolutely amazing hacker and would probably want to enlist his help to crash the Kaitou Kid fan club message board (maintained by Sonoko Suzki) just to laugh her ass off when the screaming fanbrats freak out!

Matt is Naoto's sole motivator to play video games now. I can see her really wanting to try out ICO or Shadow of the Colossus, because both games are beautiful cinematic, have intuitive controls, and are all about brain power rather than button mashing. Oh yeah, and Guitar Hero. Naoto may not be able to play a real guitar to save her life, but she appreciates good music, so at least she can PRETEND she can play!
