Vita hardware: decent. Software: FLOPPING. How much is digital?

[Branko2166]

I have bought only 5 physical games. Playstation plus provides me with a constant flow of games though so that plays a big part.
I have a 32gig memory card but am considering purchasing a 64gig as I am running a bit low on memory having so many games loaded on my Vita including PS1 games.
