Re: Umm....
Ditto on the Optus HFC - probably about 6~7 years for me. Never bothered to go with the Speed Pack as my requirements are generally not for speed and the standard connection has been doing OK.
However, of late I am unable to run YouTube at anything over 720p from 4:30pm-ish through to about 9:30~10:00pm.
I wonder what the cost will be when the nbn™ comes down our street. I suspect that: a) it won't get cheaper for the same level of service, and b) it may not get faster for the same amount of coin.
I'm always happy to be proved wrong.
