I borrowed one from a friend of mine when Time Warner f’ed up and disconnected our internet like 2 weeks earlier than they were scheduled to.
It worked great, but I was warned that even though he had unlimited bandwidth, I couldn’t upload or download anything, or play any games online. It was strictly for general surfing and getting email. According to him they will do audits on accounts to make sure you aren’t doing anything intensive.
Not sure how 100% truth that is, but that’s what I was told.
