I am already considering 'retiring' my Q40 - a big ugly box which makes a noise like a vacuum cleaner compared to modern hardware (especially my silent Raspberry Pi), with no USB support and a dodgy image on an LCD screen it's just become clutter. My only worry is that by the time the Q68 becomes a product it will already be obsolete, i.e. restricted to old type/speed/capacity of SD memory or whatever removable media type is adopted. What about support for other essential peripherals, i.e. keyboard (USB or PS/2?), mouse, monitor - HDMI, DVI or just old VGA? If it was right up to date when released I would be interested. Oh, and the filesystem would have to support any size of SD card the hardware supports. 200 euros? Maybe if the exchange rate improved to make it a lot less in sterling.
