I agree with the other reviews. Remix OS looks promising, but there's still a lot of work to be done for this to be an everyday distro. For me, I have noticed there are occasional crashes and freezes, usually without any warning. It also seems like Remix would work much better on machines with SSD's, rather than hard drives. I have noticed a lot of disk thrashing with the old hard drive I am using it on.
The installer and updaters both need some work, wifi is definitely very spotty, at least with cheap USB adapter I am using on my desktop. Wired Ethernet, however, seemed to have no issues. Another plus is that just about everything from the play store seems to work, although I didn't test very extensively. Lately, though, I've been having some trouble with the desktop. I had all my icons disappear, come back a few reboots later, and now have mysteriously arranged themselves onto three separate pages (like on a smartphone) that I can swipe through.
Anyway, I still hope that work continues on Remix OS and the bugs get fixed, because there is a ton of great software available for Android, and it really looks nice on a bigger screen.
Remix OS is probably the best desktop version of android available. It is better than Android x86 in the sense you can have mulitple applications with resizable windows as you would expect in a desktop OS. It also has a dedicated file manager and a key mapper tool for those apps that only work with a touch screen.
The cons: Wifi can be a bit flaky. On my laptop it never connects on boot, but works once you activate it again. CPU usage seems to spike a lot and the install process could be better. There should be an option to install to hard drive on a machine with no OS installed. It seems to be designed to run from USB, but Android x86 installs to HD easily enough, so I don't see why remix can't. Finally the OS feels glitchy and buggy at times as it if still needs some optimisation.
Overall I would recommend it if you want to run android on a desktop PC. This gives you the best experience as it has workarounds for non touch devices, and is quite fast and responsive on the right hardware.
Is it better than using a linux distro? Yes an no. Remix is very easy to use especially if you are used to Android. It doesn't feel like a mobile OS forced onto the desktop (unlike Android x86) and there are potentially thousands of apps you cou can try. I also had no screen tearing issues with remix which I always have with linux distros. However it isn't a true desktop operating system in the sense that gnu linux is. It's roots are a mobile operating system which may limit its appeal, but if your computer use is fairly basic, then remix would be more than capable of meeting your needs.
