Poetry is not interested in expert debate at all, and it converts the big spectrum of possible degrees of accent into those two simple categories: stressed and unstressed syllables.
If the FCC is worried about a single carrier buying up the entirety of the spectrum in the forthcoming broadcast spectrum auction, then a simple rule forbidding such an outcome in that auction is more efficacious than a clumsy spectrum cap.
However, on the other end of the spectrum and for more casual capture, the ZPen's clever, simple design competes best with the common and ubiquitous ink-slinger.
