what are the disadvantages and advantages between desktop & Laptop computers?why

well.. laptops only advantage over desktops is their portability. you can bring your laptops anywhere, even in the toilet. laptops, however, are barely upgradable, even if you know how to. you'll need to find good technicians who can actually do that. because for one, simply prying the laptop open is one hell of a job. and you'll get one hell of a big headache if you drop your laptop. just looking for an LCD replacement could take ages.. compared to a desktop, which you can upgrade almost every part. you can basically do anything you want. if any part becomes defective, replacing it would be pretty easy, specially if you know how to. c',)
