Hardly, Iwata clearly said it was a complete gamble to risk such a traditional business model by going out of the box. I think the performance deal was somewhat correct. I think they didn't want to risk losing so much money by making a powerful machine while keeping the controller concept with the Wii Remote. I mean in the end it paid off well for them (well, did)
If the Wii had better games out during the first 2 years I would've kept mine no problem. I use to be a huge Nintendo fanboy but the games just didn't really interest me much, I sold it and bought a 360 Elite in early 2008 because of it.
