A:Answer Yes, the PS Vita and PS TV (aka PS Vita TV) require the Sony memory card, which is very expensive compared to standard SD cards.
However, while annoying, once you bite the bullet and get the 32, you'll have room for more titles than you can play at any given time. With the occasional uninstall of long unused data, you won't have a need for any other memory cards, making it a one time purchase with plenty of capability. It's not pleasant, but it's definitely worth doing.
