I should also note that this article was really done to present an answer to a very common question. "whats better plasma or LCD?"
This question is almost of a religious nature and thus will never be answered to the satisfaction of all. Since you know this your article is tantamount to flame bait. But heh, it's _your_ web site so "bait" away. And here's my nibble:
The first four of the five reasons given in the article all concern picture quality (PQ). If PQ is not the most important or even a primary requirement, then they cease to be reasons to pick PDP. I'm not being trite - there are other factors that can be important in the selection of a TV, such as environment and uses other than watching broadcast TV.
Note I haven't even argued that LCD can also achieve high PQ (IMO it can in some cases). I'll spot you the superiority of PDP's PQ uncontested. But I can't spot you your fifth reason: cost. I'm not seeing, at least in stores like BB or Futureshop, a strong price advantage for PDP in the 42-inch to 50/52-inch range (which accounts for the majority of sales) among the same tier of manufacturers. Unfortunately, except for 42 inches, the technologies do not share the same screen sizes, making apples-to-apples comparisons difficult. The 50-inch LCD referenced in the article does not exist for direct comparison to a 50-inch PDP (closest is 52, followed by 47). One thing is clear - if someone should want 1080p in this size range (for reasons _you_ may not agree with) LCDs do tend to cost less.
Regarding page 2 of your article, arguing against some of the "common reasons cited for picking LCD over Plasma" I will say that IR is less common on LCD than PDP and hence there is less _worry_ (unfounded or not) over the issue of so-callled burn-in with LCD. Admittedly psychological, but real as a consideration nontheless. Regarding room brightness, I don't know what a "typical" living room brightness would be. Is that at night or during the day? And would it be considered typical to leave the drapes open during the day? I can tell you that's typical at my house and a PDP image wouldn't fair well under those conditions.
I like to say there are good reasons to choose PDP and good reasons to choose LCD, but they're not necessarily the same good reasons.
