Just throwing in a surprising second vote of support for Razer's laptop line. I've never owned a laptop that didn't have a ton of quirks, and my Razer Blade Stealth isn't an exception - but even given that, it's one of the best laptops I've ever owned. It looks beautiful, it's light, battery lasts a really long time, it handles any game I throw at it at 1080p with reasonable framerates, so I can game while traveling.
The biggest issue I've had with it was actually with the charger - the USB C port on the charger snapped off after just a few months of reasonable use. Razer replaced it for free, but that's when I learned that any charger less than 100watts results in the battery draining under load when plugged in. The build quality of the laptop itself, though, is excellent.
I've done BIOS updates, etc., and have had no issues.
