Mobile technology should not be about cramming the office into your pocket but a way to enjoy your everyday life.
I bought a perspective correction lens for situations like this - but when I need it, all I have with me is my camera phone. I have seen photos of this building before and today I realised, by accident , that it is next to the hotel where I am currently staying. This building looks quite normal from the other side - which is the side facing the hotel.
Still, I am happy I at least had my cell phone camera at hand.
