OLPC and Microsoft

Which build do you currently for the G1G1 XO. I am running the latest joyride build that
appears to be faster than the default 656. I think the lack of staff is significant even
though volunteers can get the XO image running via emulator like QEMU.
The real issue for the OLPC as a non-profit organization IMHO is the lack of focus and a good
leader who can further push the development of Sugar interface. 
Windows XP as operating system is fundamentally flawed by design. The fact Microsoft already
set the EOL made it useless. Users can always remove it and install another OS. Microsoft just
want its big part.
