For the record there is a considerable difference between the surface book and the surface pro "x". I have heard complaints about the pro in the past but as it was a fairly new product was not surprised. Now they are on the 4th edition, Surface Pro 4. I would have hoped the initial growing pains were solved. Perhaps not. The surface book is, unlike the Pro, a high end and very powerful machine. The pro is something between a laptop and microsofts answer to an iPad. I imagine your airline tried to load it up with some fairly intensive software and the Surface Pro 3 (can be bought with several speed processors, etc) was overwhelmed. But for occasional, light, simple native Windows applications such as SeeYou or SN10 utilities it is still probably OK. For the record I am not a Windows or Microsoft fan...
