sdcard isn't the micro-sd -- that's extsdcard.
I've tried pulling the micro-sd and reading it with a USB card reader directly in a PC and that works, but I'm not excited about pulling the card often as I'm afraid the socket will wear out (as USB sockets are known to do).
When I get the USB Ethernet adapter, I hope it works and produces a 100Mbps connection, but even then, I've heard that the copy/paste function of Android file managers is flaky. When I copy something large to the edge now, I have to copy, paste, then go back and delete since there is no MOVE command, unless someone knows of a file manager WITH it. Also, even the copy/paste tends to lock up my edge on large files.
How can I be a throwback when i don't remember jumping forward?
