I am no fan of UBB, or even the overage charges, but that being said, I have never had an issue. Those worrying about spam emails being counted and other minor and small traffic have a point, but a rather moot one. That is small amounts of data, KB's, not megs or gigs. In the bigger picture, its most likely not even a trickle on your monthly usage.
I would rather see Rogers spend the money instead, getting people to secure their networks. Its pathetic to see how many networks are open, unencrypted, and just sitting there. Even the password protected ones are crazy. I have seen some where the password is the network name!!!
If your usage is of such concern, spend the money and buy a better router which has these reporting abilities, or one that can upgrade the software to something better. All big business monitor their own networks usage. While I agree Rogers etc need to be accurate, I don't think the buck sits completely with them.
Too many people have bad computing habits and do not realize the ramifications of such ignorance. People need to lock down their systems, networks, and change their habits. People generally lose their mind if their wallet goes missing. They would never leave their front door to the house unlocked, yet, most don't even employ a free program to encrypt their hard drives. Proper anti virus and malware programs to stop viruses, trojans etc. I am more concerned about my data being stolen from a break in, or my laptop being stolen while working, then Rogers being a little off on my monthly usage.
I think the whole issue is much larger than just a simple UBB.
