I agree with you, its a trend that a lot of people dislike. Samsung is really about the only manufacturer that still does SD cards. Google is really pushing everyone else away from them to try to get them to use their own could based options (and carriers love it because doing so eats more data)
Curious, how much storage do you currently use? What is the main media that you use that much storage for? Photos, videos, music?
I have 32 GB of storage on my phone and have never had any issues with space. I know that doesnt work for everyone, but if you check out how much space you're currently using you may notice you can get by quite easily.
