Just now I wanted to go to Apple's home page, but I mistyped and asked to go to www.appple.com instead. Imagine my surprise when I was whisked straight to Amazon.com and presented with the results of a search for 'apples'. This surely can't be accidental. Also, surely Apple must have heard about it by now. Maybe they figure they're more likely to get a sale through Amazon than through their own web site. Based on a highly representative sample of one product, Amazon are definitely the cheaper option.
There's a 'http://www.apppple.com/' as well, which doesn't feature Apple products, and is harder to imagine anyone mistyping, though what the name stands for is beyond me.
