This thread has people hailing Dell and HP as quality laptops. In other threads, there is no end to the troubles people have with Dell XPS. HP has a poor reputation as far as I remember, without remembering any specifics, except that they had overheating issues at one time.
I guess the difference is probably between business and consumer laptops, where the former tends to be Dell or HP? Except Acer, as noted, because Acer is trash. Don't buy Acer.
It's because it's expensive paid repair service so I bought it, but I don't think I really like to repair my laptop so many times. (And not to mention classic power adaptor problem with has built-in it for pretty long time)
For Asus and Acer, we always joked them with a "built-in timer", they will break when time is up. Just like all those eco-friendly things. Very environment-friendly company.
