1. No charge for copper phone line - Orcon VOIP works seamlessly
2. No surcharge for bill payment on credit card (that REALLY annoyed me when Spark introduced it).
3. Now I can stream video on demand (mainly Netflix and a bit of Apple TV), and I can get to the end of what I am watching without it falling over !!!
I'm not saying that Spark were throttling the line, after all they deny it !!!! But, both plans are unlimited, with both ISP's I get download speeds of 13-14 Mbps at the modem, with Spark streaming always fell over after an hour or so, with Orcon it hasn't once in the last two weeks (and that's in Taupo with the town full of holidaymakers).
You can draw your own conclusions .....
