Try Stellarum N9 for interactive, up-to-date 3d sky experience, or mTimer to help you in the kitchen, MeeRun as a personal sports tracker, or Bord which is a great way to occupy a 3yr old annoying kid. How about the Incredible Circus - a perfect time killer during a long flight. There are many beautifully designed apps that still work and stand out. I've bought my third N9 last week, so it's more than just an addiction : )
