I see it the same as I see sliding keyboards, antennas, track balls, or any other outdated phone tech. Phones have evolved beyond SD cards and removable batteries. Not because the manufacturers are cheap or there isn't high consumer demand, but because there are better, easier, more reliable ways to backup, save, transfer, and access data without SD cards. So it's fine if people want to continue using them, but the evolution of phones is going to naturally move away from things like SD cards and removable batteries (and any moving parts) as technology progresses.
SD cards are like floppy disk of computers.
