The ultimate number one thing to do with this device is turn off tap to click. With that off the trackpad is okayish but still crap. i actually enjoy tap to click on Apple and Thinkpad trackpads. The keyboard is good enough and better than most laptops. not mechanical keyboard good but good in a 50g sponge-ish way. Display is a typical 1080p matte IPS screen (aka a minimum requirement for display specs for some but still within the range although at the low end.)
I will say it is valuable to have as a developer. I find it helpful to work off of a slow device sometimes to test how your widget will work as you might run into issues with timers or other weirdness, and aarch64 is somewhat becoming more common - so it might be good to test on that platform too.
I like the concept. Just think they missed a trick there.
