the main point is this..."We say, ‘What’s the best bang for the buck,’ but at the end of the day, that comes down to, ‘What’s the best bang for the bit,’” Goldman said. “When you look at the cost of bandwidth and the cost of current infrastructures, given a choice of all these technologies, I’d like to have them all. Unfortunately, going four times the resolution in a plant where people are just upgrading to 3 Gbps, you need four times that. Even in the compressed domain it takes two to 2.5 times the bits to do that"

long term cost is the driver and ntek beats them all..period
