Creative diversity doesn't pay bills. If you're going to sell one or two laptop designs, it damn well better be what the majority of people expect from a laptop.

While you're certainly within your right to buy different types of hardware, I don't think you're right to criticize convergent design. There already are wildly different laptop alternatives like the iPad, which is mainly held back by it's refusal to accept basic laptop features that Mac and PC users take for granted.
