.Yes, I think that Apple should have to replace "Defetive" MacBook Pro Computers because it is not the customers fault if they bought a computer that was "defective" the way I see it is that if it was defective then it shouldn't of been on the market to purchase anyways.
Apple should replace defective MacBook Pro Computers if there is a mass defect rather than if it is just affecting a few select machines/people. They should do a mass recall on any affected machines if there is enough evidence to prove there is a defect. People would try to send them back without defects if they don't realse a specified list of allowed returns.
As a lover of technology and electronics, I am always out to be the first to purchase a shiny new toy. I have come across some lemons when it comes to electronics - some are lemons right out of the box while others become defective way before the warranty expires. Companies are pushing out products too fast and are not checking for defects - this should not fall on the consumer. When you buy something that is so expensive you expect it to work for a long time. Replace the rotten apples!
Apple should not replace 'defective' MacBook Pro computers. This is because the computers still have value will still be used for all their features. I don't think it is wise to get rid of something that is functioning. A few tweaks are better than full replacements. It is better to make small fixes than recreate the wheel.
