Well, I dunno about that. Its a very upgraded Gamecube. Think a nice PC upgrade, otherwise same platform. And some spiffy new controllers.
Technically, if I bung in a new (for example) Socket A with lower power requirements, lower heat and more cache, and then a new graphics card, and them some new RAM, etc, it's still new technology... I think it's rather odd to decry the Wii as 'old tech' simply because it's not got the same level of sheer horsepower of far more expensive (particularly to manufacture - especially the PS3) consoles, when it's clearly built to a different spec and more around efficiency, size, etc, than just pumping polygons. Decry that design decision, sure, but the 'old tech' argument doesn't wash with me.
(yeah, Nintendos' quietness on tech specs hasn't worked in their favour here, but if we're judging technological progression on graphics alone, then we're in need of help here; hell, Moores law didn't predict chip performance but
density, technological progression is a lot more than megahertz or mips - especially as those two terms mean bugger all anyways
