Not really. If you think about it, Nintendo's consoles have never been solely about being the most powerful or streamlined, but rather something that differentiated them from their competition.
While everyone was jumping on the CD-bandwagon, Nintendo released the N64 which stubbornly used cartridges. Then came the gamecube, with its somewhat iconic "lunchbox" design. And while the PS3 and Xbox 360 were duking it out, there was the Wii which created a motion control-trend of its own... which may or may not have been a good thing. *coughkinectcough*
And in between all of these home consoles there were all the handheld consoles, which Nintendo has always managed to dominate. Even as Sega tried their Game Gear or Sony tried their PSP to get a foot in, the Gameboy and DS absolutely destroyed the competition. I mean, can you even think of a good handheld console that wasn't made by Nintendo? Not a decent one, but a good one?
And there was also the Wii U... I don't have much to say about that one, it's just a shockingly mediocre console.
Personally, I have mixed feelings about the Switch. Yes it does continue Nintendo's tactic of making themselves look different and has some interesting hybrid ideas behind it, but the thing is just so awkward and it doesn't really cut it as a handheld console, making the hybrid part rather redundant... But if the thing is good enough to house something like effin' BotW then it can't be a dud by any means!
Now don't get me wrong, I'm not a fanboy by any means. I respect Nintendo and their ability to remain not only relevant but also strong in today's market, but I also realise that they are riding a strong base of beloved titles, nostalgia and economic security. Almost anyone could make ends meet with something like that. And their run hasn't been flawless either. The Virtual Boy is an infamous example of being too ahead of your time, with a design that is really backwards. The 3DS had a rocky start to it, but at least it quickly got its footing back. And they have mishandled a few of their most beloved series lately, like Star Fox and Metroid, although Metroid looks to be making a comeback of sorts.
I've always been a fan of Sonic myself. But it wasn't because his games were the best, but rather because of his character and design. Sega could've made it big if they'd stayed focused on the simple gameplay of the early 90's, but they were the victims of poor management, various trends and the simple fact that they tried to be Nintendo yet completely misunderstood what being Nintendo is about. They thought that being Nintendo was copying everything Nintendo did, but being Nintendo is to do something different to everyone else; not just jumping on bandwagons, but creating and/or perfecting them.
In a way Nintendo is a bit backwards, in that their consoles tend to be weaker than their competition. But it's the difference between fighting a body-builder and a martial artist: One looks imposing, the other is imposing. I'd rather not pick a fight with either of them, but if I was forced to choose I'd go for the big guy, because at least I know what he's going to do...
But those are just my thoughts. :D
