Saying, "...but but but Nintendo makes it work and they lean heavily on exclusives," is to ignore the reality of Nintendo's entire history, and how the company positions the console as a product.

It may look similar on the surface, but a console for #Nintendo isn't a means to an end, it IS the product. It's goes hand in hand with the way they structure their experiences (games).

Sony and MSFT don't put nearly the same emphasis on their console(s) as part of the experience. There might be a neat feature here or there, but historically, they are there to facilitate the use of software. 

Don't equate Nintendo's ecosystem to PlayStation & Xbox consoles.
