Fine line between the genius and insanity. Love you Bird. You are a great family member.
Thanks, but you give me too much credit, bjs. I was a national computer expert for an 11,000 person agency, but that was 15 years ago, in the days of Windows 95 and 486 CPUs. Now I'm an obsolete dinosaur, learning Android from the ground up.
Bigtroutz,
No, I haven't considered trying to put the whole sdcard on a flash drive. I think if would be a PITA, because the OS, all apps, & so many other things expect and automatically read & write to the sdcard.
I like my current setup, because I don't need the USB-OTG dongle for most uses, and only connect it when running my data-intensive astronomy and birding apps, or when retrieving backups.
