i fix computers as a part-time job. from what that comes in, there's no best brand, all equally good. customer bring it in when it starts to lag or it doesn't start up. if that's the case, it's all software. i hardly get laptops where it's a hardware issue, unless it's a coffee spill or dropped. operating system are becoming more reliable, and company's are building the laptops way better than they did years ago. it all depends on what you want to do with the laptop. gaming? better video card. graphic applications? just more memory. simple business task? any of the top brands will do fine.
