First of all, everybody knows Sony is crap. So don't buy their shit and complain afterwards.
But second, they offered to cancel the whole deal, but Vincent refused. Another reason to not complain. Although most laptops are sold with Windows, it is possible to buy one without. Dell for example sells FreeDOS / Ubuntu laptops. He should have picked that one.
Apparently there is not enough market for non-Windows laptops. If where him, I would simply buy the laptop I want, removed Windows, installed Linux and used the Windows license to install Windows as a virtual machine. Always fun / nice / useful to have a small Windows installation at hand. Just in case.
