You're right. Blu-ray has just come out and of course it's going to have some bugs.
I know something else that's completly new that has had no reported problems and I would say it's a bit more complex than Blu-ray: The Wiimote and Nunchuk. All of it is pretty much completly new and powerful, but like everything Nintendo, it lacks what Microsoft and Sony generally have: bugs.
The PS2 had a lazer problem that overtime, destroyed the console itself. The Xbox, while my current favorite console, had problems with it's first consoles and with it's powercord just last year. The Xbox 360 has heat problems and the notorious "red light" problem (sort of like the blue screen of death, which is a problem in Windows, which is another thing Microsoft is behind), and now the PS3 is having problems before it's even hit store shelves.
I'm just saying one of the things that will be great about Wii, like every single Nintendo console before it, is it's dependability/durability.
