Is it a Nintendo system? (Yes)
Does it have Nintendo games on it? (Yes)
Sold. Simple as that. You guys agonize way too much over this stuff, even assuming only a 4 year life cycle $250/4 years = $1.25/week.
$300/4 years = $1.44/week.
Oh noez. $1.25 buys you what? Like one whole McDonalds cheeseburger a week? Live a little.
In hindsight I regret not buying every Nintendo hardware, even the 64DD and Virtual Boy. They are well worth the price as collectibles alone. I own every other major Nintendo hardware from the NES onwards. NES, Game Boy, SNES, N64, Game Boy Color, Game Boy Advance, GameCube, DS, Wii, 3DS, Wii U.
