This has Windows 10-S & I hate it. So I registered this laptop thru Microsoft & then turned off the "S" mode for good on this laptop. It comes with Microsoft Edge as its built-in Internet browser....better than prior MS browser IE. I also installed Google Chrome as my 2nd Internet browser too.. 15.6" monitor....good picture quality. Horrible sound quality. This is the first time I had a SSD drive like what's installed in this computer & it's small in capacity also at 128 gbs. It's not a old-fashioned mechanical or newer solid state hard drive, but a very small newest type of hard drive that connects directly to the mainboard with no wires or cords. It's about the same size as laptop RAM memory. This computer is very fast operation-wise. I had to buy external units on both for this laptop. Why Acer deleted the DVD/CD burner unit & SD card reader on this device is beyond me since they are rather thin in nature on laptops anyways. Lit keyboard...stays lit for maybe 15 seconds.....interesting feature and wished it stayed lit all the time. Needs at least 1 more USB 2.0 or 3.0 port. 128gb Solid State HD.....makes it speedy to power up. Only 4 gbs of memory.....which I order two 8 GB SODIMM RAM for more memory & speed for this device.PROS:Great picture quality on the 15.6 inch screenSeparate numerical keypadVery fast laptop [due mostly to the small SSD installed on this laptop]Lit keyboard [only stays lit for maybe 7 seconds tho]CONS:NO SD card readerNO DVD player/burnerOnly 3 USB ports [could use 1 more USB port]Cannot add 2nd hard drive inside laptop for added storageSmall 128 GB SSDComes with Windows 10-S modeIF Acer could have put in a 520 GB SSD, added 1 more USB port, added a SD card reader, add additional 4 GB of DDR4 RAM [to make it with 8 GB of RAM total] & somehow shoehorn a DVD player/burner into this laptop....you'd have a winning Acer laptop that's still rather thin/slim. But as it is now, I'd rate this laptop 3 of 5.
