It's not necessarily about brand loyalty. There are a few brands I would be very wary of buying in almost all fields of purchase. But honestly to say "I will never ever buy from X again" is to predict things about the market and myself that are simply not predictable.

I like the n900. No, I love it. But I bought it for what it is, not who makes it. I'm not one of those brand loyalty people who buys whatever 'my' company produces without thinking (just as well when you look at Nokia's ramge! ). But to ask me now if I will ever buy another? I could say I think it extremely unlikely I would ever buy an Apple product. But even then I can't say 'never'. Who knows who'll be making what in ten years time?

People are so prone to these global statement "I will never ever..." "That's finished me with..." Life is long and markets and manufacturers change.
