Many of the laptops do not carry an International warranty. If you can't deal with shipping it back home for your parents to handle the repair and then back to you with a 4 to 8 week delay you better get your international warranty laptop.
No, as the warranty changes from make to make, I leave you to do that research.
Soon, I will go to university in South Korea, and I will take business as my major. I have been considering macbook air as my laptop, because of it's performance, and weight. But, I also have been confused because a lot of models out there. Is my consideration good enough as a business student? Or Do you have any opinion about other great laptops for a business student? Thank you for solving my problem
