Pros: Beautiful, bright screen. Backlit keyboard is nice. Extremely fast, will run any game I throw at it in Ultra 1920x1080. Case is actually more attractive than it appears in the photos here.

Cons: Upgrading the hard drive is not for the faint of heart, you have to completely remove the keyboard and upper shell of the case to get at it. The hard drive isn't even attached with screws into the chassis, just resting in a foam bed. Battery is also not removable without disassembling the case. I suppose this explains the low price.

Overall Review: I immediately replaced the HDD with a SSD. This thing is silly fast now, will boot into windows in under ten seconds. It can open LibreOffice in about 2 or 3 seconds. Definite improvement from my old Core 2 Duo!

Pros: It works, sort of.

Cons: I tried to use this with two old Commodore computers (VIC20 & C64) and the picture quality is awful. Unusable really. Not worth my trouble to return it.

Overall Review: Don't buy this, it's junk.

Pros: Pressing 'W' results in 'WEEEEE' , comma results in backspace. 'M' results in 'W'. I've got a pile of dead logitech mice to add this junk to. Not worth my time to return it. Into the trash it goes, and I'm not buying anything from logitech anymore.

Overall Review: Would not recommend.

Pros: Small.

Cons: Died after two years, never really worked well and was super-slow.

Overall Review: Junk, glad it was discontinued.

Pros: FAST. FAST. FAST. Screen is bright and beautiful. Has extra drive bay for another SSD or hard drive. Storage is done on an Intel Optane M.2. The specs here aren't clear about that.

Cons: I hit the Windows 10 time zone bug when setting it up, no fault of Acer. Delete your Windows "cloud cache" registry key if your Start Menu tiles keep getting messed up after changing the time zone.

Overall Review: Love it. Couldn't be happier.

Pros: DDR3 with ECC for my NAS box.

Cons: Expensive!
