I have a jtag'd falcon and I honestly haven't turned it on more than ten hours since I jailbroke. Right now the ps3 doesn't have anything to hold over a jtag except the psx emu and the only for ps3 titles. All of the security hasn't been defeated on the ps3 so it isn't as open as the xbox is but then again it has only been three and a half months and look where the ps3 is now just about on par with xbox that has been fully exploited for over a year.
