Best laptop -- ASUS
Best CPU's -- Intel i7 Mobiles
You cant classify laptops like this.It depends on every brand's model or series.You can never say that all laptops from this brand are great and all laptops from this brand are bad.
Ok lets take your example for instance.
Asus has only good sevice in some countries.In my country Asus's service is pathetic.Not only that they didnt even have an Asus service center for laptops until 2010 Q1.
Asus only had service centers for its desktop components.
And i7 mobiles are the best performing cpu's and mostly for desktop replacement laptops not for a light gaming and portable laptop.a core i3 will suffice the classification will be divided into use first and then in models
