Leaving patent law aside, wouldn't more distinct products be more innovative and lead to greater consumer choice? I mean if you look at a company like Lenovo, then they have their own distinct design language that they inherented from IBM, you imediatelly recognize one of their laptops from a distance. Compare this to the handful of aluminum and chicklet MacBook look alikes out there, they apparently think it is better looking than anything they could possibly come up with themselves. I think they would do better by standing out on their own merits, and it would lead to more options. I don't know what causes this but a lack of imagination and being overly risk averse.
