Hi Giga,
Thanks but none of them has real time clock (RTC), so I will stay with my own board. Without RTC one can not use it in real world applications that require scheduled timing.
@Beja
I am not sure about the clock because I have not researched all of the boards. However if you follow the link about 3/4 down the page it shows also the "higher performance boards". Which shows Windows 7,8 support and others OS's. The Gizmo 2 has an int. RTC according to the diagram. @sorex
That's a nice one too. Love the compact design.
