Part of the solution for those shortcomings is not to go out too much (love to shellter in our basement) and not to take cabs all the time (altough cabs are funny enough dead cheap compared to Amsterdam rates).
Anyway, I try to avoid the tube during peak hours at all cost, but sometimes there's simply no other way.
So I'm pretty happy with this great article @ Hack the Day. Next time, I'll be prepared!
