No matter how you want to justify it, a price drop by that much in that short of a time is just a sleazy move by any standard. I did not feel cheated by the GBA SP, or the DSlite & DSi. But this was unacceptable.
Businesses doing sleazy moves to make a profit? Haha, stop the press.

Cephi's 100% right. She's not justifying anything. She's just telling you the truth. I could've easily afforded a 3DS at the time. I decided to wait because I knew it'd not only eventually be cheaper, but it'd probably come in a color I'd like a whole lot more, plus better games would be out for it then. I mean, this is standard Nintendo practice....hell gaming practice in general. Did Sony offer any sort of compensation for the people who actually spent the original $600 on the PS3?
And as for this...
No. They had to do something. Early adopters would have rioted, metaphorically (or maybe literally too), over this if there was no compensation for them getting completely [tornado fang]'d over. Which would have lead to lower profit. They instead found the cheapest way to help smooth over the situation.
Early. Adopters. Wouldn't. Have. Done. [parasitic bomb].
Reggie could have come on stage, shrugged his shoulders, possibly laughed and walked off, and gamers wouldn't have done anything. They'd go on the net, whine & complain, other gamers would laugh at them for not waiting seeing as how pretty much everyone knew it would be cheaper later on, and then they'd continue supporting the product and buying the games. Gamers are addicts, and gaming companies of every kind have them by the [tornado fang]ing balls.
Only a technological device like a gaming system could literally have a 56% failure rate at one point and people still buy it, support it, and continue to deal with it after having sent the damn thing in 3 or more times. 15% is already unacceptable for pretty much every other high end tech device, but the 360 managed to survive and people will throw down another $400-$500 for the 720 when that comes out. People will buy the PSVita when it first comes out as well, and eventually Sony will drop the price on that as well. Call it a hunch, but I doubt they offer anything for the early Vita adopter.
There was 0% risk in losing profit lowering the price like they did, cause the people that bought it still bought it and will most likely continue to support it, so they don't factor in, and the sales were going to massively increase due to the lower price, better colors & bundles, and better games out for it. Sleazy or not, it is pretty much a FLAWLESS business strategy and it works every damn time because they know exactly who their market is.
