I don't agree. The 360 and PS3 whilst maybe not as powerful as the Wii U provide overall a far better gaming experience. Apart from the Gamepad second screen the Wii U doesn't provide anything new. The online service on the Xbox is far more sophisticated. The PS3 has Playstation Plus. The online stores and account system as well as how content is tied to the account is far better on the PS3 and Xbox. Transferring content from one console to another is far easier on both platforms. The media playback capability is far better on both then the Wii U. The PS3 is region free. Do I need to go on. Nintendo has a lot to learn about the user experience.
You make a valid point, but IMO MiiVerse is innovative and fresh as far as Online gaming communities go. The control options with the Wii U are far better, but game dependent in many situations.
As far as digital downloads and content management, they haven't done too bad for themselves, and I expect they'll continue to grow the offerings and let the platform evolve like Microsoft has. I subbed to PS+ for two years, and it was worthless. Still worthless IMO. Live is great but developing, nurturing, and evolving an online community takes time and resources, I don't see any evidence to suggest Nintendo isn't making an effort to make things better.
You may consider your arguments realistic but I don't see them as such. You are, in fact, holding Nintendo to a different standard. A strong launch isn't strong if it's Nintendo, innovative controls and experiences aren't innovative if it is Nintendo. Nintendo has three months to do something many journalists and fanboys will happily give Sony or Microsoft years to accomplish. Complete rubbish. You keep saying that Wii U "may" be "slightly" more powerful than PS360 but that conversation isn't anywhere near concluded. Most developers still don't have the foggiest idea of what this hardware is capable of. All we know for sure is that with little to no time with final hardware and running code optimized for a completely different hardware environment, the Wii U can handle unoptimized X360 code. We can see from recent announcements game environments that absolutely murder the best of what the 360 was able to offer, but only time with final code on games built for this system will tell.
Also, Live, even for subscribers is littered with advertisements, which to me kills any user experience I might have had. The only thing I've ever found Live useful for was multiplayer. Their social features have gone completely unused except for trying it out after they released. PS+ was even more useless for me, because it wasn't necessary for online play and the only reason I subscribed was for the free games initially. I've used MiiVerse more in the first two months of owning the Wii U than I did in 6 years of Live as far as social features are concerned.
NNID's are new and I expect that system to evolve as well.
