I bet with DLC more than half the space of that 8GB card is taken. Simply ridiculous. I don't understand why 32-64GB isn't the normal amount of storage for a device with 48% digital sales.
You admit your device is used as an iPod for games but you refuse to give them storage to support such a use case. Way to nickel and dime your most enthusiastic customers Sony. Absolutely pathetic. The very first iPod in 2001 had 5GB of storage. 2014 you have 8GB. Cheap $100 phones come bundled with more storage than this. If this is competitive as you chose to be then you deserve the low sales.
