As I had mentioned previously in another thread - when my Logitech Revue died I ended up buying the Acer CXI2-4GKM chromebox. I liked it a lot although there were a few minor issues. Mainly with the two-finger scroll on the trackpad being a bit "clumsy" on some web sites. Also sometimes on YouTube the mouse cursor can be a bit laggy and "jumpy". But overall I would of rated it about 4 out of 5 stars. Web surfing was fast and web videos worked good. However yesterday I was scrolling through some YouTube videos and my Chromebox just stopped working. The web page was frozen. I couldn't get anything on the keyboard to work. So I tried turning off the chromebox (and unplugging it) - but when I turned it back on it wouldn't boot up. There was no signal. It was "on" because the blue light in front was on - but the light just kept blinking which was wasn't normal. I spoke with Acer support on the phone - and we tried a factory reset from the pin-hole in back. But that led to getting a screen that says: "Chrome OS Is Missing Or Damaged". Nothing we tried could make it boot - so next there's supposed to be a way to re-install Chrome OS via a USB drive or a SD card. However it requires a second computer which I don't have. So I took the Chromebox over to the "Geek Squad" at Best Buy. They tried to re-install Chrome OS but they couldn't get it to work. They're thinking it might be a hardware issue. But who knows. I searched on the internet for "Chrome OS is missing or damaged" - and apparently this is not an uncommon problem and it happens on various other Chrome OS devices from different manufacturers such as Samsung and Asus. Which makes me wonder what is the real cause of this issue? Anyway I had a 1 year warranty from Acer - so I sent it back in to their repair center. However I had to pay the shipping. After it's fixed they will pay to ship it back to me. Seeing as how it died after only 10 months - I would probably only rate it 2 stars. We'll see what happens when I get it back from the Acer repair center - but if it dies again within a few months I'll probably move on from chromeboxes and try something else with my next purchase.
