I've been running Windows 7 x64 and Snow Leopard in dual boot since about a month before Windows 7 was released. I don't think I had to jump through hoops to get Boot Camp set up either. Might have involved a single command line operation.
I had my launch Wii start making a weird clicking sound about 6 months ago. Everything worked fine, but the system was a lot louder than normal. I called Nintendo and they sent me a prepaid shipping box. I sent the Wii to them on a Monday and received it back on Friday, 4 days later. Everything was fixed and there was no charge. My system is over 2 years out of warranty. Nintendo has some of the best customer service of any company I've ever dealt with.
