So given all the "checks", if it isn't PTK, then it is concerning no?  One thing that is routinely gleamed over here- and an inherent flaw in basic logic to my mind-if we really have a technology that nobody can possible replicate or find alternative paths, then why aren't NA Tier 1's engaged, why would anyone walk away from having an edge that nobody can touch, according to what we argue here?  Makes no sense.  Do people not see the gap in logic here.  Build it and they don't come, but do their own thing? I don't get it, and the market suggests I actually do.
