I've been pretty consistent over the years in what I think is most important to a phone. I've never placed much priority over microSD or removable batteries. Removable batteries is only great when the phone is old and you really need to exchange the battery. Luckily, the GS6 has a way to do that. And as for microSD, just give it up. Use wifi and use the cloud, buy an external USB key for your car or something, and get as much memory as you need from the get-go. Stop clinging on the past.
