Acer Chromebook 14 CB3-431-C5FM vs Lenovo Chromebook C340 15 (2020)

The metal body and size no doubt add some weight compared to smaller, plastic Chromebooks, but at just under 3.5 pounds it's still light enough for a daily commute or hauling around campus. Plus, the rounded edges make it easier to slide in and out of a bag. Perhaps because it is so thin, though, the keyboard's keys don't have much travel

One thing that surprised me but shouldn't is that this machine is way heavier than our Lenovo X1 Carbon gen 4. 2.7 lbs vs 4.3 lbs

I charge it often at levels of 50%, 70%, or 90%. Both laptops get about 9 hrs of battery life if use both at 45% screen brightness. Hopefully this battery can last me for 10 years. I usually keep the display for the Toshiba at 50% screen brightness for videos and 40% for browsing

Battery life, even with the back-lit keyboard and larger screen is very good. I have used it for a whole workday unplugged, while listening to music and it lasted well over 8 hours with some to spare.

Video streaming - runs 1080p Youtube videos just fine. I have Chromecast and I've streamed pages with videos from this computer and found that watching videos and surfing the web really hampers the performance, that's another disappointment. Fanless processor - no noise, love it. At first I was disappointed with the performance (coming from a Acer C740), but after a week of only using this chromebook it has grown on me

As it's a Chrome OS device with a low-power Intel CPU, it can only handle simple tasks like web browsing and media consumption, so it isn't ideal for any demanding workloads like video editing or 3D animation. Unfortunately, the display looks washed out and doesn't get bright enough to combat glare. Also, the webcam's image looks dim, and audio through the microphone sounds staticky.
