I've written a long, thorough review of KaOS 2014.12 64-bit KDE edition, an Arch-inspired distribution, tested in a quad-boot setup on a laptop with Intel graphics and SSD, covering live session, supposedly failed installation due to a bootloader error, and post install use, including look & feel, network connectivity - Wireless (2.4GHz and 5GHz), Samba sharing, no printing, multimedia playback - MP3 and Flash, installation wizard, partitioning and associated errors, applications, package management, missing software, desktop effects, resource usage, stability, suspend & resume, customization, other considerations, and more.
