@is dthrp serious?
I understand what you're trying to say, but not sure if you're actually familiar with these systems. You don't have to believe me but I've used these laptops in person, and Aero 14/15 (daily driver) as well as a similar laptop called Clevo P950HP6/HR both have good build quality compared to what I've been seeing from both manufacturers in the past. To clarify, I recently used MSI GS/GL/GE builds as well, and I'd put these two above them. Not sure if you knew, but both of these are constructed out of partial aluminum and a tough plastic material called Polyphenylene Sulfide (PPS), which is a polymer alloy used on many high-end business laptops as well, the Thinkpad T470p for instance.
Clevo P950HP6 (here's the Max-Q model review -
https://www.notebookcheck.net/Eurocom-Q5-Clevo-P957HR-i7-7700HQ-GTX-1070-Max-Q-Laptop-Review.244590.0.html) starts from US$1250 where I live, so it isn't terribly expensive either, much unlike the premium/business options you mentioned which all have poor/non-existent dGPU selection. You may disagree, but business grade build quality hasn't been all that useful for me, and I'm a type to throw around my laptop and not handle anything with much care. Long before, I actually used a Dell Inspiron for 4 years without any issues. MIL-SPEC - don't need that either, not taking it out into any open extreme conditions. Yes I know all about Macbook/Razer build, I've used them but more importantly, my brother broke the lid off his MBP 3 times, then switched to the Blade and dented the keyboard area to an unusable state and eventually had to pay for his err of judgement. Strong chassis no doubt, but certainly not durable when it comes to "accidental-shock-resistance".
I'm aware of the keyboard issue, somewhat weak hinges, bad touchpad and audio compared to macs, but no laptop is perfect. For the specs, the XPS 15 9560 and Zenbook Pro UX550 are ridiculously priced imo, and I didn't even consider the Aero initially because it was also simply too expensive (US$2,100) compared to Clevo and Acer models I've been eyeing. So I considered Gigabyte P56XT (1070 + 8 hour battery life) which was US$2,050, but due to poor thermals, just settled for the Aero. The build quality is quite similar to my old Inspiron, so I expect it'll last 6+ years but I'd probably sell it for a new laptop before hitting 3 years (which is when their value starts to quickly diminish). Plus I like a lot of things about this laptop - 2 removable ram and m.2-2280 ssd slots, great keyboard feel, small form factor, factory calibrated display (which helps loads because games tend to ignore custom icc profiles), etc. All the features that I couldn't find in any other laptop, so that's nice.
