Yes you will miss out on some apps if you buy a Nexus 4.
You will also miss out on some apps if you buy an iPhone.
Almost all of the highly used apps and games have versions for both the platforms and you can always find an alternative.
I don't think you will need all the apps that are available on these platforms, so make a list of apps that you are using or would like to use and we can check if the android app for the same is available or suggest an alternative.
