An interesting study here coming as it does from a failry new source.
http://www.zeropaid.com/news/9822/UK+SURVEY%3A+86%25+Don%27t+Understand+Broadband+Connection+LimitsWith data caps slowly becoming the rage these days as ISPs try to combat the amount of network traffic that illegal file-sharing consumes, it's interesting to learn that many Internet subscribers are unaware of the limits placed on their connections.
Their research reveals that 6.2 million broadband customers wrongly believe they have an unlimited broadband service and a further 7.5 million do not know what their limit is – a total of 13.7 million confused customers. This has apparently led to almost 1 million consumers nearly reaching or exceeding their limit in the last year alone, an issue that could be avoided if providers clearly stated their "unlimited limits."
With over 16 million broadband connections in Britain bandwidth usage is growing. As streaming video applications and services such as the BBC's iPlayer become more popular with consumers the unlimited issue is only set to worsen. Unfortunately, broadband users are completely unaware as to how much their activity adds up to in terms of their overall usage. Even activities such as uploading files can contribute to their "acceptable usage" and could cause users to exceed the data caps set by their ISP.
No one minds capping and throttling if thats what they signed up to, the problem is many didnt and are now facing the scenario of having to accept these pathetic limits or have no service due to their ISP greedily overselling their services, users who had decent deals should be protected from ISP back-sliding of this sort , its not like the price of the service ever drops to match the reduction in quality.
