How about McDonald's golden arches, or maybe the JolliBee bee in the Philippines. Actually, I ate at the Jollibee in Tagaytay and it was better than McDonalds.

Gio, the thing with nazi logo is that it was gaining huge popularity in decades before nazis (early 20 century). I much recommend to read an article in Egnlish wiki.

I was going to became second popular symbol with unspecific meaning of 'bringing luck' (and some specific once as well) - much like the "star". Then in 1921 Hitler took it... and here we are: nazi have an impressive symbol of their own:-/

For me is the windows logo beause many people use it in their computers.

I think the cost of printing in full color was annoying to Apple, and that the main reason for the change was economy. The current one has a certain austere beauty to it, but it's like eating frozen yogurt when what you want is a banana split.
