I'll get right into it.-3855u/4GB RAM-Keyboard feels very good, nice and firm. Not a ton of key travel, but definitely enough. I'm very happy with the keyboard. The keys are not wobbly like I've read about other Acer CB's.-Touchpad is on the large side, very responsive to gestures, nice and slippery, and feels accurate. Physical click is decent, I've never had a CB with a "very good" feeling physical click, this C771 is probably the best I've had. My Toshiba Chromebook 2 2015 had a -horrid- mouse click.-From full, battery life estimates 11 hours with a few browser windows open and a handful of tabs in each window. Screen brightness around 90%-Build quality is excellent, this thing feels so solid that even though it's all plastic, it feels like a well made product.-Only has USB C on the left side, sucks for charging when you need to charge from the right.-Speakers are nice and loud, although there is a little vibration in the case somewhere.-Screen brightness is good, haven't used it in the sun, yet.-Screen colors and contrast are good, not great.-Screen viewing angles are good, not amazing. Definitely sufficient.-Micro SD card sits flush when inserted, thank goodness. I hate it when they stick out and can eject themselves.-It's pretty thin considering it's built to be tough.-I'm already dual booting GalliumOS, installed via chrx without a hitch. Sound doesn't work on Skylake CB's, though. For now I have a USB audio dongle.-I wish the lid had a bumpy/grippy texture to it, considering I bought it to bring everywhere, including outdoors. It's not slippery, but it could be more grippy like the R11.Can't think of anything else to add. So far I love it, it's everything I hoped for! Aside from the lack of texture and USB C on both sides, that is. I was considering waiting for the i5 version, but I'll have this device with me all the time, so the idea of a $280 device at risk rather than a ~$500 device is a lot more appealing.
