> Anyway, the "bricked" expression is more commonly used in smartphones and PlayStation Portable (PSP) than laptops. Then it makes more sense when considering the size of the devices.

I think it's also at least in part more commonly applied to those types of devices because they're generally more locked down than a laptop, leading users to risk bricking by trying jailbreaking them. Installing a custom OS on most laptops just isn't nearly as risky in terms of bricking potential.
