A few weeks ago we had a healthy bit of a debate on gigabit services and their use on fiberevolution. I didn't delve too deep into the debate because I was working on a report on that very topic. The report has now been released, it's called The Gigabit Race is On! and it examines the gigabit experiences around the world, the pricing strategies for gigabit services and the strategic meaning of launching gigabit services.
(Incidentally, I have decided to post about Diffraction Analysis reports here. I think they're infrequent enough that it wouldn't be an issue, but let me know what you think!)
