FWIW, the loss of the SD card in the Note 5 is a harbinger of things to come. From what I've been reading, most, if not all, phone manufacturers will be getting rid of SD cards in phones, as they have been a huge pain for both users and the manufacturers. Plus, they cost the manufacturers money and space. It costs them money, because you can now purchase an inexpensive SD card rather than pay for upgraded internal storage. It costs space, because we all want a very thin phone - and having a removable back costs space, in terms of how thin the phone is. And if you can't remove the back to change the SD card, there's no easy way to replace the battery. Plus, just peruse this forum and you'll read about LOTS of issues with SD cards. Although cheaper, SD cards just aren't as reliable as internal storage.
If they up the internal storage, that is all that I need. From what I've read, Samsung will be getting rid of the SD card option in all of their phones, and most likely, the replaceable battery option as well.
Personally, I'll miss a replaceable battery, but, frankly, I don't swap batteries very often - but it's nice to know the option is there when you need it.
