There are 3 in my family, a 9350 and two 9360s. All work fine. I represent the majority of people who have no reason to write anything about their computers because there's nothing to say.

Accepted (apart from the unsubstantiated claim about representing the majority). To quote myself, these perceptions are only based on "anecdotal & biased samples". The problem is that a lack of accurate & reliable information can be a great incubator of unsubstantiated perceptions. I'm just suggesting that if the Dell team believe the XPS's not to have reliability problems, it's in their interests to come up with tactics to manage perceptions where possible. It's in our interests really, as we all would want a wide range of good developer-friendly laptops available.

I also own 9360 with 1080p panel for half a year. The only thing that bothered me was adaptive brightness (CABC) that was fixed in my case with an unofficial panel firmware at some risk to brick the device. Coil whine is perceptable only if I keep ear close to the keyboard. No other problems. If there is someone from Dell here: please fix CABC! Unofficial patch proves that it can be done. It's especially important for linux devs who switch between dark terminal windows and browser: CABC increases backlight brightness if contents of screen are light, and decreases if it's dark. So, I switch from terminal to browser, brightness jump is already unpleasant as is, but then CABC kicks in, increases brightness and burns out eyes. Switch back to terminal -- too dark, difficult to see anything. How it's even supposed to work... Another unpleasant thing happens when CABC starts to adjust brighness back and forth while I edit code, it's highly annoing when it happens. Edit: There were also a problems with Atheros WiFi, but new firmware from Atheros's github fixes them completely for me. Works stable since June 2017.

  Tool from Dell to disable CABC on the FHD model was released today. Happy days! http://www.dell.com/support/home/us/en/04/drivers/driversdetails?driverId=312K3 http://www.dell.com/support/home/us/en/04/drivers/driversdet...

  Adaptive brightness is a Windows setting you can change in the Power Options control panel. Click 'Change plan settings' next to your chosen power plan, click 'Change advanced settings', click 'Display', click 'Enable adaptive brightness' and change it to off.

    I don't have windows installed, but it's highly unlikely that it'll help. This feature is baked into panel firmware, and while Dell releases firmware updates for some models, there is no official fix for 9360 FHD. For models with the fix there are two versions of firmware: with CABC support and without. Switching requires firmware reflash with a special vendor tool. So it's unlikely that there is a dynamic setting to switch it off.

      Oh. The setting works in Windows on my XPS 13, but I have the 3200x1800 display. I disabled adaptive brightness the day I bought it, because it annoyed me for the same reasons.
