We still have lots to do – in particular bringing the Windows desktop version on par with the Mac one in terms of user experience and stability. Since we're Mac heads, it's hard not to put the Mac version on higher priority first.

We're also rolling out a Chinese version of the app interface and the website, as well as a bunch of features like “secured” connection with encryption very soon as free updates.

The pricing issue is a tough one, we've had some long debates over it. We hope by providing a “trial” version later will help potential buyers “test-drive” the app and appreciate its quality before making a purchase.

As you said, Finger is inexpensive as compared to a “real” writing tablet, but not so when compared with many other iPhone apps. This is something that we need to work very hard on – to let people know that it is not just an iPhone app, it's actually a desktop solution that saves you from buying / carrying a tablet around.
