About the take the plunge from the iOS world (which is ALL I know!) to a new Galaxy S4. Unfortunately, AT&T still has no idea when the 32GB will arrive. And coming from a 64GB iPhone 5, that stings a bit. BUT, most of my storage is photos and videos. So popping in a 64GB xD card should do the trick. My only concern is any lag from the card to the phone when viewing photos and videos, as well as saving them once they've been taken. So I want to make sure I get the latest and greatest technology in an xD card. What should I be looking for? Any links to fairly affordable ones? Thanks in advance!
