Most of the story is true but a little biased. Fibre comes in different forms and has varying lifespans. If it take on consumer grade which I expect it will do then the lifespan is fairly accurate.
Speed well the more obvious concern with the NBN report is Fibre run at maximum data rate level so unless they are going to run millions of fibre connection one to each home the sync speed might be 100Mbs but the combine speed when multiplied over the number of houses the speed restriction would be the same as what we experience with ADSL 2+. Also depends on the main fibre link from the junction to the exchange. I cant imagine they would install one fibre link to each house.
There would be no real benefit to increasing the speed with the exception of upload speed which fibre can do. I had the pleasure of running Annex M Adsl 2+ which gave me an increased upload speed from 1Mbs to 3Mbs. That alone allowed me the ability to run 10 concurrent VoIP telephone calls easily. This is more than enough for anyone. All internet traffic except voice and video require th same upload and download speed to operate. This is really what they need to work on and to cover remote and RIM areas first before anyone else.
The issue of 4G though is the same as fibre. With data radio the more connection the lower the signal strength becomes. They can only trasnmit the signal to a certain level before going no further. So the more connection the less the speed. Again like all sales people (Government) they take maximum theoretical levels to acheive the best sales pitch and for most people they love to hear these high figures. Lets face it though if you advertise the full story in detail most people wouldn't go for it and the government would lose on that issue.
