There are distro respins available that offer a more tailored experience and everything working out of the box.

Con Only 8GB RAM
8GB RAM is way too little these days (becoming completely hopeless if you happen to need VMs).
Con Poor color accuracy

Con So-So screen
At only 720p the Acer c720 definitely does not have that great of a screen. However, it is fairly bright(230 nits) and has surprisingly good viewing angles (75+75 degrees) side-side, and maybe 20+20 degrees up-down. The touchscreen (c720p) models have a glossy screen and are a little bit brigher and clearer than the mattscreen models.
Con Includes a fan
The Acer C720 does have a fan built into the device as it's faster i3 Intel processor does need cooling for the more tasking operations.
Con Shallow SD card slot
The SD card slot is shallow which means having a card in it will stick out a bit.
