Sweet, it said data not found, but I guess that's because I'm on a laptop with no GPS, however I just typed GBP to EUR, something I do on google quite a lot, as well as basic maths calculations and it came up with charts and everything right on the result.
Typing in an airport code gives a pretty cool result too.
Any other cool stuff I should know about?

Must remember to use this more often
