I just wanted to provide some feedback to those who may be considering the Asus S500CA. I spent a lot of time honing my search for an ultra portable 15". It basically boiled down to this machine or a Samsung. Based on the price difference, I went with Asus. I'd also had really good experience with Asus motherboards in the past.
I picked it up from B&H Photo for 650. Great deal, right? Well, let's just say that it is not just componentry that suffers with a price this low. The build quality is terrible. My machine had black dirt between the glass panel and the LED display. Not dead pixels, dirt. I don't know how this could have gotten past QA, but then again, there were other more minor quality issues like screw covers glue out of place that make it very clear this machine passed by no QA eyes whatsoever.
I wasn't overly fussed as I heard Asus has comprehensive warranty support. Well, again, a big disappointment. After a week, Asus confirmed they would send me a replacement laptop, as the repair parts would take too long (outside their 5-7 day return window). The next week, they changed their minds, and decided I *would* have to wait for the parts to come in....no replacement for me.... my time is not that important right?
2+ weeks later, and still no laptop, no forecast from Asus, and very little from Asus except "regrets".
Let me assure you, Asus, the regrets are all mine.
