Last month was word of Android-x86 joining the company behind Remix OS, an Android-based OS designed for PCs and laptops. Out now is the Remix OS Beta that's leveraging the Android-x86 project.
The Android-x86 project site posted the brief message, "Remix OS for PC - Beta version built on Android-x86 project is available for download." This beta version of Remix OS is available for free download from Jide.com, the company behind Remix OS.
The Remix OS Beta is available in a 64-bit flavor with UEFI & legacy BIOS support as well as a 32-bit ISO that just supports legacy BIOS systems. This beta has over-the-air update support, a hard drive installer, and many bug fixes.
