You might be having an idea that Nokia N9 doesn't have HDMI-Out support but a good thing is that like other recent Nokia devices N9 supports TV-Out feature to deliver the output of your smartphone to the big screen you have at home.

As developers were already working on it and in result you, if have N9, now have an application to run the hidden FM Receiver in your N9. A developer at MeeGo community did a nice job to bring you the first QML based User Interface with underlying appliction to execute the FM Receiver in the Nokia N9's hardware.
With the help of Developer Mode in Nokia N9, you can transfer files and other data including music and videos as well from/to device via WiFi and SSH within the same network.
Nokia Store is however there for you to get additional apps or games or any thing for your Nokia N9 but sometimes there are some reasons when you want or need to install apps that are not on store. e.g. some developers want their apps to be tested before publishing over to store so they could provide you a standalone installer file to run on your device.
Nokia has recently release a software application for Windows and Mac to connect and sync your Nokia N9 with your computer. Well Nokia N9 will not be there with you yet so far as it's just on the way to hit markets. Preparing yourself is always better. If you have any plans getting a Nokia N9, Nokia Link is for you.
