Alan at RMR has sent over a beta (you'll be able to grab it yourself very shortly) of his flagship RMR Bank suite running under NS Basic and the StyleTap (Palm OS) emulator. If that sounds like a bit of convoluted development chain then I think you'd be right. What's of most interest are that the end result does work but that simply porting a stylus-based app to S60 isn't always a good idea. As you'll gather from the screens below, operation partly involves driving a cursor (Web browser style) around the screen. Also of note is that the application menu is on the right soft key and the Style Tap menu sits independently on the left function key.
It's early days for StyleTap on Symbian though, so don't take current behaviour as proof of how it'll end up.
