I'd love for this to evolve into a "World Traveler" multi-function app like Palmary Clock or Fizz Traveler.

1. Currency Converter that updates
2. Common Conversions (Imperial to Metric, Clothing Sizes)
3. World Clock & Weather function (i.e., time & weather in the cities you specify--good if you are on a multi-city trip or when scheduling meetings and tele-conferences with clients in different time zones)

I'd love to see it all in one place. But, on the other hand, we already have a good app for global weather and Nokia's clock is passable. I suppose that since the tablet has limited memory, I'd rather keep the footprint small by reducing redundancy. So, an all-around converter with a focus on currency would still be very useful to me.
