Has anyone done the update on XP? My main laptop is a Macbook, but it would be easier to do it on the PC!
My money says the M$ XP will work fine. Just don't plugin the SXmini until you have installed the SXmini Setup program. and completed the driver install from the SXmini update program.
XP has always be friendly to me but it has a problem at times if you plug in a device it doesn't recognize then install the driver it sometimes gets confused. If this happens it can be corrected so it is not the end of the world but just a headache you don't need.
I would also guess that the people that wrote the Q&A that Vlad1 posted aren't old enough to remember XP.
