My thoughts on the Fusion idea:
The clear benefit is that Nintendo can focus on ONE system, on ONE ecosystem instead of two. They'd release a hell of a lot more games, thus avoiding the droughts we've seen on 3DS and Wii U.
The games could/would range between AAA level and portable and indie levels, and Nintendo could offer them in accordingly price ranges; $60, or $30, or even $5. You could play a $60 AA Zelda game on the go, or a $30 platformer on the big screen. That gives the costumer options – we looove options!!
The important thing is to make the games scalable! Lower textures and lighting on the portable version and higher on the home version, kinda like the PC's already doing. I'm pretty sure that this would save Nintendo money in the development department; not having to spend $10 million on the next Mario, maybe $5m would suffice.
Nintendo wouldn't be dependent on 3rd party support (which most often is sorely lacking on their platforms), since they'd spit out a game or two EVERY month!
Speaking of 3rd parties; with ONE ecosystem with TWO devices the instal base would be a lot bigger than on only one console with one ecosystem, the cost of porting games to the Fusion would be a lot less risky since you could cater to a lot bigger audience. And let's remember that Sony probably won't make a new handheld after the Vita (the handheld market is a lot smaller these days, and Nintendo is dominating that market). There obviously IS a (somewhat small) market for AAA experiences on a portable device; just look at Call od Duty and Assassin's Creed on the Vita. 3rd parties could cater to this market, AND to Nintendo fans – at the same time – by porting games to the Fusion. Ain't that a treat?
I'd sell it in THREE (3) different SKUs:
Only the Handheld, bundled with a HH friendly game (say NSMB or a 2D Zelda) for $200/250
Only the Home Console, bundled with a “pro-controller” and a HC friendly AAA game (say 3D Mario or Zelda) $250/300
Both devices and bundled with a game and maybe a pro-controller for $400

Furthermore, I think VGChartz should add a "Like"-button.
