Would it be possible to have *two* PCIe Mini Card slots, say one for WiFi and one for 4g/LTE? That would be awesome. Mom hates cables, and I mostly agree with her on that... so look much easier, with the router in the front hall, to run WiFi rather than Ethernet to the kitchen table, two rooms and ~30ft away...
