Thanks to the Udoo team, Debian 7 "wheezy" armhf "maximal" arrived on December 12. Here are my comments from a posting on a different topic: viewtopic.php?f=2&t=470&start=20 The LXDE GUI on wheezy is light and snappy ... suitable for a single board computer. There is software in abundance via APT. Ubuntu is "billed" as a "desktop OS". Linaro is a port of a desktop OS to ARM, an interesting concept with lots of corporate support. It worked and it was fun, but there were a few problems. Identifying monitors correctly was one I experienced frustratingly. Even though Udoo is the strongest single board ARM computer I've used, LXDE on Debian seems (a subjective judgment) closer to the snappiness of a desktop experience to me than Gnome or Unity (especially Unity) on top of Ubuntu. Just an opinion. BTW, and most important, wheezy is just as fast with hard floats as Linaro (follow the link above).
