Don't get me wrong, I actually -like- the system and it might very well be the first console I buy since the PS3. But practically speaking, I don't think the rest of the market will view this console as favorably as I do.
Clarifications of my original response:
By "me too" I was referring to the original post's point of going x86 in a traditional TV box in the way that XB1/PS4 did.
By "struggle", I was specifically talking about third party software support in the post I replied to. On the TV console front, Nintendo's primary strength going back to the Wii (and maybe further) has always been first party games. Most of the third party games on the Wii and Wii U were not very good. In other words, if you're buying a Nintendo TV console for the third party games, I think that would be a big mistake, regardless of how long the list of committed 3rd party developers is.
Addressing some of your points:
>> Their mobile products are, in essence, "me-too" products that are larger and less powerful than a smartphone
By "mobile products", I assume that you're referring to the DS/DSi/3DS - how are those "me-too"? What other successful portable consoles have that clam shell form factor? If anything, Nintendo's mobile form factors (starting with the original Game Boy) were the ones that were historically copied by others.
>> The years when the Wii outsold the PS3/X360 are not all that far past. If they come out with something different and compelling, the market will respond.
Yes, but the market for gaming is completely different now. Games are no longer the exclusive territory of proprietary tv consoles or portable gaming devices (i.e., psp, 3ds).
On the TV console side, Steam is a legitimate substitute for a TV console. I myself switched to Steam since most of the AAA titles I played (2D/3D fighting games) are now all available on PC and I can bring them with me in the form of a laptop with a discrete GPU. And with Steam, I can regularly upgrade my hardware with full backwards compatibility for my purchased games.
On the portable gaming side, phones and tablets have basically taken over the market. The only reason why I bought a 3DS is so that I can have my fill of 2D/3D fighting games (with a real controller and buttons) in my pocket, but I'm in a very small niche.
