I'm not so sure, Kairon. The scenario sounds a bit iffy, to me.
He decided to buy the $200 Wii for his children for Christmas. He tacks on additionally prices that are inaccurate, to say the least, and not even necessary. He looks at the game selection, and decides Wii Sports is enough for his kids. He goes home, and talks to his wife about how he spent about $90 more than he had originally planned.
Then, suddenly, he realizes he'll have to create rules to go with the new gaming console. Suddenly, he realizes that the Wii, itself, could overshadow the other gifts he got his children at Christmas. Suddenly, he realizes there's other options.
A responsible consumer and a responsible parent would have considered the cost of buying a Wii for multiple family members. He'd know that instrument-based controllers can cost extra, or else Best Buy wouldn't try so hard to sell them to you. He would know that he'd have to make sure his children played the games responsibly. He's already told us he's already done that with the free games on his computer his son plays. Of course, if he was planning on limiting the amount of Wii time his children would get, he'd also know that they would certainly appreciate their other gifts, as well.
To me, it sounds like he found it was too expensive, and decided to make several excuses afterward. If he's someone intelligent enough to read about in an advice-style column, then I'd venture to guess he'd be smart enough to understand what's involved with this decision, and a sharp enough critical thinker to foresee at least one of the trouble-scenarios he divines after he made the purchase.
I suppose the article may be an attempt at how to be a responsible parent, an educated consumer, and a rational human being, but not in what you pose as the intended nature. We observe from the journalist's poorly thought out, potentially erratic behavior the complete opposite way a responsible, intelligent, and rational person would go about making a purchasing decision for his children. In essence, that's why I believe most reactions to this article I've seen have been quite a bit negative.
