He quite possibly didn't have any issues, but if he was aware of the problems so many have reported, it would surely be prudent to mentions them? Again, why wouldn't you if you knew about it? Suggests he was oblivious to it all. There are MANY MANY owners who have had a very different experience to yourself... you can't single out this thread, a bit of reading elsewhere shows a different story.
Well, Acer's QC has proven to be rather shocking actually... you will find many people agree with that. I was most likely venting some anger following my frustrating experience with the XB270 (which may explain my tone in some of those posts) most of which had dirt/dust behind the panel. So no, I don't like them in that regard, but if I had confidence in one of their products I'd happily buy it, and a full and thorough review would go a long way towards that. I really don't think asking for a full and all-encompassing overview, warts and all, is asking that much tbh, but I guess we'll agree to disagree that this would be a positive thing for everyone.
