You cannot so casually dismiss the period of overlap. However, I do wish the N800 was still currently produced. Also, I'm not limiting my comments to the current status quo. I'm not really hinting that there are solid plans for broad diversity, but I think we can all agree that would be the (ultimate) necessary state.
Only if you utilize it.
I think we can all agree that there are cost/benefit analyses we all perform, even if they're instinctive and emotional. Will I buy an "NxxxHSPA" even if I don't use it and the extra cost is $20 USD? Yes. $40 USD? Maybe. $80 USD? Doubtful. But you get the picture.
I just think people need to calm down a bit and not turn the addition of an HSPA radio into the Internet Tablet Apocalypse. "Kill the platform"... sheesh.
