“The system of using removable SD Cards on Android cards are not secure because they are formatted using Microsoft’s old FAT-32 file system. “
Very true, but they come in handy for :
1> Storing MP3s, video, and pictures locally. Helpful if you don’t want to pay for WiFi on a flight or if you’re driving through West Virginia on your way to pinball machine auctions in North Carolina :-) ... data is spotty in those (and many other) areas regardless of carrier. I typically keep several albums and a few movies on my phone just for trips and what not. I also keep a few Google Maps for offline use too.
2> Storing massive amounts of pinball machines for Pinball Arcade (games in general require a lot of storage ... more than your average app).
3> Storing loads of other “useless” data for emulators and the like.
There is plenty of use for unsecure SD card storage. I would hope that Google would support SD cards for general data storage only (not application or “critical” data). While data access to the cloud is certainly better these days, it’s nowhere near “perfect”.
You and I are somewhat on the same page on this.
