I bought this laptop for my wife, who uses it for her eBay business which includes lots of photo post-processing, plus all the other usual things people use computers for. It was to replace a 10-year-old dell that she was complaining about being slow and having a less-than-stellar display.The first thing I did when I unpacked the laptop was to turn it over, remove the bottom panel, add another 4GB of RAM and a 500GB SSD.  I ordered these from Amazon along with the laptop. I left Windows 10 alone on the 128 GB SSD that came in the laptop, which was fine for the once or twice a year she needs Windows to update her GPS and a few other things like that.  But she wasn’t about to use Windows in her everyday life.  I installed Linux Ubuntu 18.04, IMHO the most stable and all-around dependable OS available today.  I run it on several other computers, including my own that I use for creating Web sites, among lots of other business things.The laptop now default boots into Linux, but if she wants to use Windows, she just needs to click on it on the momentary boot screen that pops up when booting or restarting the laptop. Linux plays well the Acer setup and connected to wifi, our two wireless printers, Bluetooth and everything else it was supposed to do without a hitch.  It works fine with the Acer display adapter, too.She’s totally happy with it for performance, the dazzlingly clear and bright display and even the built-in speakers (although she usually uses earbuds). Web pages snap into view instantly now, something that wasn't happening with her old laptop.Anyway, for the price plus less than $100 for the 500GB SSD and the 4GM RAM upgrade, she has a laptop that cost about half what others with its capability and performance would have cost.And also, it’s thin and very light to pack around.  Can’t speak to battery life because it’s plugged in most of the time.  Not to worry, though, since the battery is replaceable if and when she ever gets to that point.We’re happy!
