I do contend that the remote definitely does make some games immersive and the controls feel intuitive, but that's for the Nintendo titles I've played. They made the same mistake with the GC, in modeling their controlling for first-party titles (Zelda! Mario!) and not really anyone else.
That said, I really did enjoy the Metroid Prime 3 demo (a lot!), and I'm not the biggest fan of the first two. And the system is capable of pumping out better visuals, but it's foolish to think it'll ever match the Xbox 360 or PlayStation 3.
I think this is the first time that the company line of marketing their system to another demographic, which is often a convenient excuse to explain lower sales of a product against the competition, is actually true. Nintendo has pretty much marketed the Wii out of the videogame industry. It's like a toy and it has caught on with the mainstream, but it's more like a karoke machine than a videogame console in terms of use and enjoyment.
