Have had my SP3 since it came out really and have loved every minute of it. Took a flight back for work on Monday night and fell asleep during the flight. We landed, I got up and grabbed my bag from the overhead and walked off the plane never realizing my SP3 was nice and comfy in the seatback pocket of the airplane. Was beat when I got home so I went to bed and didn't even notice until the next morning it was gone. I filed a report with the airline for lost items but I don't have much faith it turns up. They say they get 30 days to attempt to find it. It's bitlocker encrypted and I have a pretty strong password so hopefully it means if someone picked it up there isn't a lot they can do with it. I'm really bummed and now have no work machine. Have to use an old HP laptop for the time being and it's just not the same. I didn't think I would become so attached to a machine but that thing did everything I needed. TLDR: Don't put your Surface in an airplane seatback pocket.
