If you're hacking your Vita, which is relatively easy, there's no reason not to get an adapter. Sony memory cards are notoriously expensive, $100 for 64GB? You can get that and a 128GB SD card for less than half the price and more than double the storage. This works well, uses the spring mechanism in the bios and works in tandem with the Storage Manager plugin.
