I am not loyal to brands when it comes to almost anything I buy. I buy cheap chinese tat (if it will get the job done I want) right up to high end stuff. I never go to purchase something and make a consideration as to whether I actually like the brand as a whole. I almost find it odd that people do. Everything is bought based on what you are getting for your money.
I've had hardware over the years from probably almost all of the main PC hardware manufacturers. I've never had a number of failures associated with one brand more so over another, including hard disk drives.
I've had a number of Asus motherboards, graphics cards and probably some other products I forgot about. Never noticed any issues with Asus. If anything, their motherboards I found better. Currently 2 of the 3 PCs in the household have Asus mobos. Faultless. Just bought an Asus laptop because it's a good deal and fulfils the needs/specs I want. I have no concerns with the latest Asus warranty stuff tarring the trust of the brand. To me I'll still evaluate my needs based on price vs spec/quality. Asus are no different.
