Netrunner comes from the same stable as the much acclaimed Linux Mint and Kubuntu - the Blue Systems is the sponsor of all three distros. It is built on Kubuntu with default integration of Gnome and Wine (though Wine dropped in the present release!) to offer users powerful customization, high functionality and an attractive interface. Plus, all the goodness of Ubuntu. The release note of Netrunner 13.06 states:
"The 64-bit and 32-bit variants of Netrunner 13.06 are available for download. Features and changes: new Netrunner desktop containment (no cashew, hidden plus/minus overlays); improved KWin performance, so full transparency works on most lower-end machines; new Kate minimap scrollbar; automatically activated KWallet; hot corner in lower right; simplified system settings; removed WINE (due to increased irrelevance); ALSA instead of PulseAudio for best compatibility and performance (intel hda); Firefox with (working) Mozilla app store; Steam installer link included; usual KDE goodies - Homerun 1.0, Tomahawk 0.7."
Normally I download 32-bit versions of most of the distros. However, for Netrunner, I could not even after repeated attempts. Hence, I had to download the 1.4 GB 64 bit ISO (my laptop is 64 bit, but 32-bit with pae kernel works really well on it consuming lower RAM and even a lot of the apps I use like Skype, Adobe Acrobat Reader, etc. comes for 32-bit Linux).
Netrunner 13.06 has KDE 4.10.3 as the default desktop with Linux kernel 3.8.0 and Dolphin 2.2 as the file manager. Post installation, it got updated to KDE 4.10.4.
