Nintendo is no stranger to hardware iterations. Its last portable, the Nintendo DS, saw several major revisions. The 3DS is a different story. It just came out a few months ago but is already seeing half-hearted hardware upgrades. (A snap-on second slide pad? Ugh.) And 3DS owners should be pissed.
The 3DS has been a cold, greasy buffet of Nintendo mistakes. Even for Nintendo, from whom we can expect multiple hardware iterations, everything was so sloppy, so unpolished, so expensive, and ultimately, so un-Nintendo.
