Excellent article, Rob, and you raise some interesting points.
It's also refreshing that an article critical of the Wii does not mention its last-generation graphics, or Fruity iMac-level CPU - these are, after all, of little importance to Wii gamers, and simply blank ammunition used by anti-Nintendo fans who equate technology with "fun".
From that omission alone, I get the inference that you're coming from the right angle - could it be you're seeing ahead of the curve here?
I can't see myself waving my arms in front of the telly for hours on end - for starters, I'd get winded. Contrast this to marathon sessions of Gran Turismo or hours playing CRPGs/TBS on the PC, and the value proposition of the Wii starts to drop. Maybe Nintendo are doing me a favour here - I can go out and enjoy the fresh air when I get tired, and for once, gaming will be, I can't say healthy, due to the insane risk of RSI (Nintendo Shoulder, anyone?), but at least active. However, a gaming platform that I can't play for more than 30 minutes at a stretch, or when there is a crowd in my living room (which is pretty small), is simply not worth the investment of USD$250 (or worse, AUD400 if you're an Aussie).
Re: The web browser, why aren't they using Opera? (like, say, the DS). Or if they are, why isn't it working? It seems more and more, companies are rushing out half-completed consoles with the aim of fixing them later, only they need some quick cash first (Of course, Nintendo is not alone here *cough*Sony*cough*).
Lastly, I don't think you need to keep defending your article. Let it stand on its own merits. Readers may not agree with every one of your points (I certainly don't), but a rational reader will approach it with an open mind and make their own decisions. So will any true Nintendo fan who wants the company to to keep moving in the right direction - see what happened to sony when they got their head stuck up their head and thinking they knew which way the wind was blowing. You don't want the same thing happening to Nintendo, do you, people? As for the fanbois, they've already made up their minds, there's no point wasting your breath arguing with them.
