Last week saw a boatload of Windows 8 product announcements at IFA in Berlin, which is great if you're looking forward to Microsoft's touch-friendly OS next month. But if you're an open source fan wondering where all the love for Linux is at, well, you just have to know where to look. A good place to start is ZaReason, which is now selling a Linux-based Ultrabook , perhaps a first of its kind.ZaReason's UltraLap 430 is a 14.1-inch laptop that measures 13.5 inches by 9.25 inches by .75 inches and weighs 3.5 pounds. That's Ultrabook territory, and so are most of the customizable hardware specs, which consist of an Intel Core i3 3217U processor, 4GB of DDR3-1333 RAM, 32GB mSATA solid state drive, 802.11n Wi-Fi, multi-card reader, 1.3MP webcam, and 6-cell battery. It also has HDMI output, GbE LAN, head/microphone jack, two USB 3.0 ports, and a single USB 2.0 port.The real selling point is the operating system. Buyers can choose between Ubuntu 12.04 LTS, Kubuntu, Edubuntu, Debian 6, Linux Mint 13, Fedora 17, or no OS at all.The UltraLap 430 is available now starting at $899.
