MIDI Keyboard/Computer: Neko64
An anonymous reader gushes "Just got back from NAMM, and saw the coolest thing for music geeks - it's a MIDI keyboard with a dual Opterons and a 15 inch touchscreen. While other vendors crow about 5 inch screens (Now With Color!) these guys have a beautiful UI on a live performance instrument that is also awesome studio gear. 4 interchangable control surfaces, and battery backup to boot! If the power cord gets yanked out in the middle of a performance, there's plenty of time to bitch out the roadie and get it plugged in without missing a beat. These guys truly Get It."
but does it run Linux?
