Basically you have to find out what works for you. If the available memory works for you your good, if not than get a phone that will. That's the beauty of android. I used to not buy a device without expandable memory until I had my tbolt. It came with a 32gb microsdcard. I used about 14gb total between music, video and apps. So I know 32gb internal is way more than il need in the next 2 years.
SMH at no MicroSD card. I'm not an engineer, but it's such a simple thing and has always been an advantage over apple.
I stream a lot of stuff, but I also travel. I can't exactly stream movies, music, etc while at 30,000 feet.
It's not simple when the phone is a single piece of polycarbonate. You're talking about something that the entire phone would have to be engineered around to make sure that it we on an outside edge and accessible. Easy for the sim. But a sim and a microsd? Not so much.
