Make that "a lot of people who dislike the design speak up about it". The complainers are always a vocal majority. Especially people who complain about lines that they don't even see while using the phone.
When they went from the rounded design of the 3GS to the "flat" design of the iPhone 4, there was also a lot of complaining. In the meantime, it turned around to the iPhone 4 being considered a "design masterpiece".
Luckily, I don't buy phones based on what they look like, as I actually use them, as opposed to them being fashion accessories. My phones go into a case anyway, so as far as I am concerned, they can add pink blinking LEDs to the back. I knew someone once who bought CDs and books purely based on their cover. Goes somewhat in the same direction for me as buying phones based on their design.
Agreed. Nicely said.
