We recently upgraded our broadband internet service to NBN and have been relatively happy with the increased upload and download speed of our new service ... we stream all of our television the the internet so this has been a huge improvement than using ADSL for the same requirement, we were however forced to use an internet supplier branded modem which is proving to be substandard and is unable to handle all of the devices we use in our household. The service often has to buffer to view high definition video and seems to have some kind of compatibility issues with apple devices of which we use more than other electronic devices.
All-in-all though, a great improvement.
