I'm developing a currency convertor for the nokia tablets and just looking for any feedback on whether people would find this useful?

The screenshot below is the current state, still very early days and needs some work to its options and interface etc, but still does what its supposed to.



The features will include;

* Live internet updates on exchange rates (currently auto updates on startup)
* Options to choose rate data source
* Saving exchange rates for later offline use
* Save selected from/to currencys between sessions
* ... and anything else which you might find useful?

Let me know what you think.
