Recently, news has surfaced (no pun intended) that Microsoft's tablets don't actually leave all of the advertised storage space available to the user - much of it is taken up by the Windows OS.
Does the same apply to Windows phones? If I get a "32 GB" phone, will all 32 GB be available to me (plus or minus some possible discrepancies due to metric/binary unit conversions) or is some of that taken up by the OS? Is this something that varies between manufacturers, with some manufacturers advertising the total storage while others only advertise the storage actually available?
Note: I'm aware there might be some variance due to applications pre-installed by the phone manufacturer or carrier. Here, I'm only asking if the Windows OS itself takes up any of the storage space the phone is advertised to have.
