I was reading an Ask Slashdot question about VoIP. I also got a magazine a few days ago that I suspect the questioner may receive due to his timing. I can't get my head around why people want to use VoIP in manner just like POTS in which you pick up a phone and dial. I can look at how I use[d] my cell phone to make calls. I'd scroll through a bunch of names and hit call.
I see two possible futures: Battlestar Galactica or Star Trek. Both are in star ships, but the former had your typical land lines and the latter had communicators that everyone carried.
The question I'll pose is: what future do you dream about?
Not good comparisons
Right now everyone dreams of the Star Trek world, I think. Just hit the button and say "Computer: locate La'Forge!" and it does so. But Battlestar Galactica is a bad example - they purposely chose to keep hardlines for a single reason: they don't trust computers. Would you after millions had been killed by them?
