Agreed. I don't think anyone alone hopes to dethrone the iphone. Everyone targets them because they're most recognizable name right now. Droid apparently will not be limited to one handset. This is good news for Google and the customer
Also, the same posters and some media outlets introduce the "iphone killer" tagline to either garner more readers and/or in this case to immediately delegitimize an alternative product.
They had the chance, but they laughed and called it a joke in so many ways instead of doing something of their own. Now all they do is copy and we see iphone killers one after another going down the drain. A rounding error, huh?
