There appear to be at least two versions of the Mini 1012 motherboard. I have a Mini 1012 with all the bells and whistles. It has three mini PCI Express slots for wireless card, broadcom crystal video encoder and one other spare WWAN slot.
Recently I purchased another Mini 1012 on ebay. It was a more basic model with only one mini pci express slot which was taken up by the mini wireless network card.
