i have a wireless card right now and it really backfired on me when my mom's boyfriend's Xbox 360 managed to pick up on my shared folder, which for some ungodly reason linked in to my porn stash...
I fucking hate wifi, to know that my porn stash was just available for anyone to look at, and i was living in a fucking apartment complex too.
I thought I turned network sharing off but apparently the windows 7 beta doesn't label its settings very well
