Just got my laptop today. It is AMAZING. totally exceeds my expectation for sub-200 dollar. I was a little worried because it's so cheap, but now never regret.

  • build quality. it's metal all over. really sleek. feels good. much better than my 600 lenovo plastic one.

  • type-C charging.

  • HDMI

  • 1080p display is great. Not IPS but good enough for watching youtube. Hint: turn the scale to 125%. otherwise font seems too small for me. I may give it to parent. if so I will change it to 150%.

  • micro sd card reader is awesome! I don't have to find an adapter all the time. And can extend the storage to 512 GB if I want. (Just wait for a micro sd card deal!)

  • wear braces only at night while asleep

    • helps straighten wrist

  • leaning foward puts too much pressure on wrist.

  • put monitor closer or make font larger so that no learn forward

  • pad on left; vertical mouse on right. use pad for scrolling, two finger; use mouse for more precision pointing.

  • move arms instead of wrist sometimes so that not only wrist stresses.
