Well Funbike, don't get me wrong here. I'm not optimistic or indulgent about the ROG 6, and I agree with you that ROG 6 has many issues. "It's too early to tell" was ONLY meant to respond to the dead motherboard issue part of the original question. The dead motherboard has been the most fatal issue with ASUS for years, with the ROG 5 series being the worst of all and would make anyone wonder if there's any QA at production at all -- the waves of users reportedly having dead phones after merely 3 to 5 months of use after the release, and this is the time point that ROG 6 is at now. We would need to wait for a little more to observe if a huge wave of dead ROG 6 is coming, hence why the phrase "for now" was used. It'd be interesting to see whether ASUS breaking up with Enok and paying more to Foxconn to produce the phones would actually pay off.
Software- and firmware-wise, yes, the ROG 6 is definitely still filled with numerous bugs and issues here and there, and the audio is definitely just one example of those that many users have had poor experience and problems with. It's just amusing how they still haven't managed to fully resolve the audio wizard issue since last August, so I wanted to point that out specifically
Objectively speaking the ROG 6 is nowhere close to being a value-for-money phone; it's too darn expensive, and anyone would say it's overpriced. The initial pre-tax starting price of 1000 USD (or for whatever price it is set at whatever place you are at) for a phone that is sacrificing camera performance, durability, long-term software support and all other aspects and comes with several compromises is not really worth it.
