It is rare to "brick" your PC by installing linux/windows. Phones are different because their input/output interfaces are limited to a single usb port, and in many cases that usb port doesn't even support host mode. Technically the phone isn't really bricked, but there's no way for a normal user to fix it without cracking open the phone to attach a jtag.

If PCs in the 1980's could be destroyed simply by improperly installing an OS, you bet manufacturers would void warranty for software misuse.
