I'm kind of the same way. SD Cards are just of no use to me but there are some people who are adamant about having them. The only use case I could ever use it for is on-device music and video for those with a limited data plan. Most people don't want to stream it cause it heavily hits their data plan. Although, even though I have AT&T, I hardly hit my cap when streaming for my commute to work.. Although, I get the argument for a 'long plane ride' and wanting to have a few movies on deck. Although, most planes are installing Wifi on planes so...ugh. If you seriously need it, why not? Go hog wild.
