For laptop , buying at official  and other place doesnt matter to me. as long as its is a New Unit...since the black ops thingy is a violation oredi..1 more thing....when u open a new laptop for the 1st time.. it shud be like PREPARING WINDOW FOR 1ST TIME RUN...........if you are so naive believe new unit already set up desktop interface for u.. think again....the initial mindset is WRONG already.
