Jide Technology has released Remix OS 2.0 as a free download available on January 12th designed to run on the majority of Intel and AMD devices such as PC and Mac. The company which was founded by three ex-Google employees has developed the OS thanks to a partnership with the Android-x86 project enabling it to run on almost any PC.
This is pretty much what Android on desktop and laptops - what Google itself is currently working on - is going to look like. It's designed first and foremost for Jide's own devices, but starting 12 January it'll also be available for select generic x86 devices, including some Macs. There's no proper up-to-date compatibility list as far as I can tell, so we'll have to wait and see just how useful it can be.
It looks quite interesting, and the fact that it's run by former Google employees gives some hope regarding its longevity and legitimacy. That being said, with Google itself working on bringing Android to desktops and laptops, you have to wonder how much longer Jide can maintain itself.
