cyberhub: Interesting, I have been a big fan of Powershop for ages, I really like their online and iphone app. It is cool how you can prepay for your power etc. Seemed like the only power company embracing technology and trying to empower their end users.
Flick is also up and coming in this area, empowering consumers, technology to make it easier will follow.
Unsure how prepaying things is new or cool. The active management of a passive utility, ie Powershop, never appealed to me.
