When going up against the big-names (in my case, Siemens, Omron, etc.), the product needs to have that big-name look and feel. There are some very nice project boxes out there but at the end of the day, they still scream "hobbyist quality".
Not all of us are circuit board designers. We just want to write code and to be able to easily interface with whatever needs to be interfaced.
Tibbo have a great solution for this; not only do they offer pre-built modules but they also offer empty enclosures for custom designs. I am not too crazy about their own motherboard because their C/BASIC languages have some silly omissions such as a clock/timer with millisecond resolution.
Now a P1/P2-based motherboard would allow budding entrepreneurs to develop/launch Prop-based products in no time.
