I was looking for a low-cost computer for linux use.  This model was appealing because (1) it has a 1080p display, and most cheap laptops still have 768 line displays; and (2) it uses a decent Ryzen CPU, which is pretty fast and low-power compared to some Celeron CPUs you still see out there.I purchased this Acer and also also a 500GB SSD.  It was easy to install the SSD following a youtube video.  Opening and closing the case was a pretty smooth operation.  Everything went smooth.  Ubuntu 18.04 installed flawlessly.  Many times, when installing linux, there are issues with sound drivers or trackpad drivers, but everything worked great right out of the chute.  However, the HDMI out port was not active.  I did not spend any effort trying to get that to work.After the good experience, I bought a second identical unit, but this time without the SSD.  The laptop itself has 128GB of storage. Ubuntu used about 10GB, so there was plenty of room for what I needed to do.  However, even after much effort, I was never able to install Ubunto onto the main drive in such a manner that it would consistently boot up.  Also, executing "apt upgrade" always placed it in a non-bootable state.  (The first unit had no problem with "apt upgrade".)  Nonetheless, it was still usable.  About two weeks later, the laptop started getting hot and unable to hold a charge.  I returned it and Amazon replaced it with another.For the third unit, I purchased a 250GB SSD, installed it.  Everything worked fine, just like the first one.  It seemed like it took a little more effort to get Ubuntu to install onto the SSD, but that could be my imagination.One thing that is really nice about the laptop is the screen.  For a low cost computer, it has very good resolution, colors, viewing angle.All in all, it is a great laptop for linux work.  Purchasing an SSD might make the installation job easier.
