Is the console design responsible for the sales?

[daactualfact]

This has always intriqued me. Each gen's winning console has looked better than the rival consoles. For example: The ps2 was nice and slim. Yes, it looked like a box. It looked like a manly, sexy box. The xbox, looked like a giant beast! It was huge! And i'm sure some kids were scared of it with the huge "X" on it. The cube's design is one of the reasons why I think it failed! It looked like a kids toy! It'a main color was purple! I mean, most consoles start off with a white or black color then goes on to others. Another bad thing was that it was shaped like a lunch box! what do you think?
