For example, there are at least four apps for the N9 that give you encrypted storage of your online passwords, etc, behind a master password, one of which is a paid app. But in my view none of these is worth installing on my N9, because none of them are compatible with any other similar application for Windows/Mac/Linux/Maemo etc that I already use or would like to use in conjunction with the N9. I don't understand why these developers have chosen to re-invent the wheel (four times over!) and each develop their own database format, when there are existing solutions off the shelf out there they could just use and which would provide this huge step-up in (in my view, necessary) functionality for the user.
