I know I was less than a model student as far as school and IT facilities went and I do know I would've pushed that little bit harder if (the computers back then had USB and) I'd had the Switchblade at my disposal... VaKo does have a point, it's not personal systems so much as public terminals; Schools, colleges, libraries, photo kiosks and even your offices machines at work... with the ability to be modified to spread itself and all, I think it could be something of a problem there...
On the flip side though, it will indeed teach the admins of those machines to keep an eye out...
