Mobile is killing this market faster than anything like a charger inclusion.
Contracting and killing are different things. The charger, stupid as this whole affair is and excluding it being a stupid move, means very little in the whole scheme of things. In fact that contracting market is likely why they are trying to maximize profit on the N3DS... there's just not much of a market out for it anymore. Its old, its dated, and this is a stop-gap.
The moves regarding this, the N3DS, show that they have little to no confidence in the device selling to anyone but enthusiasts. NoA, or NCL with regards to NA, currently has very little enthusiasm about the market here with regards to the 3DS.
Also, to top it all off, the contracts around the proprietary hardware and making the 3DS have to use some obscure powering source, costs them money to produce, package, and deal with when they could just use micro-usb, not have to worry about contracts, and not have to worry about packaging anything more than a tiny usb cable if at all.
I truly do hope Nintendo steps up its game and the value proposition for the 3DS' successor with consumer friendly moves such as a proper online account system, better hardware specs, and a region-free console. Then again, Vita has all of these things and is doing abysmally.
Hardware wise, Nintendo is being paramountly stupid.
Software wise, Nintendo is giving us not-100$+ Prime, cross-buy, and cross-promotions... finally.
I swear the company is Jeckel and Hyde.
