Again, sounds like, because of this Android is your only option. Although, with said scenario above...ur Micro SD card is still pretty worthless. Because with all that security at work, odds are you can't store your own video files on it to transfer stuff to your micro card. Honestly, i get ur point in some situations in would be beneficial, but with high speed digital transfers via NFC, cloud, etc. it will soon be a thing of the past. Its like arguing for a cassette against an ipod. YES in certain situations it could be beneficial, but those situations are rare and far outweigh the times when the alternative is convenient. At this point, all the micro SD card slot does is waste precious space in a phone when it does what other features of a phone can already do. When manufacturers are trying to use every ounce of space, they are choosing to leave out a storage slot when everything can ve stored to the cloud, internal hard drive etc. hell, even Google left the Micro SD card slot out with the last Nexus...
*EDIT: Don't forget streaming via Netflix, Hulu, HBO Go etc
