eurotrip day 1

For technical reasons, at least for the time being I'm going to have to be very selective about how many photos I publish here, just saving the truly odd or visually decent ones...
Safely in Paris. loving the app CityMaps2Go-- even without paying for data roaming you can preload maps and then know where you are!
You know, from a UI perspective, toggle push buttons that change the state of a system are kind of problematic. If the current state isn't immediately clear, than it's ambiguous if a button should tell you what the current state is, or what the state will change to if the button is pressed.

For example, my cellphone has a virtual button "Speaker On", and if the other person isn't talking, I don't know if that means the speaker is on, or will turn on if I press that button.

I see this a lot with music players... there's the convention of the right pointing triangle for "play" (and a square or two vertical lines for "pause") but often it's a guess if it means "playing" or "play".
