AidanS:+1. TBH, I think a 50/X plan should have been introduced from the get go. The 30/10 to 100/50 is too big of a jump in both speed and price. The 30/10 is too similar to a good ADSL2+ connection (bar, upload speeds) and the 100/50 speeds are "too" much for the '"average" for the next ~5 years or so.
Fibre 30/10 is a racing car with a 50kph speed governor :)
