If you're curious about loading up the KDE Plasma Active desktop on your Google Nexus 7, here's the state of KDE in the mobile space.
Ruediger Gad, a Linux developer, has posted a video (embedded below) showing off the rather nice state of KDE's Plasma Active on the Nexus 7. The video shows off the Plasma Active user-interface, hardware-accelerated 1080p video playback, a gaming console emulator, Bluetooth support, QZeeControl as a remote control, and 3D hardware acceleration. Plasma Active is the KDE project for providing a UX platform that's modular for a variety of form-factors like tablets and smart-phones.
Google's Nexus 7 tablet has become quite popular with different Linux mobile development communities for showcasing new open-source mobile opportunities. The Nexus 7 is backed by a NVIDIA Tegra 3 SoC with quad-core ARM Cortex-A9 processor, 1GB of RAM, 16GB or 32GB of RAM, and a 7-inch 1280 x 800 HD IPS display. By default, Google ships the Nexus 7 with Android 4.2 Jelly Bean.
