ALOT faster removing the SD card and inserting it into an external card reader (vs. using the cable)
I am sure this would be true if I were, oh, say twenty years younger. And had fingernails of any length. As it is I am 67 with weakish eyes and fumbley fingers and no fingernails to speak of. I cut them as short as possible so I won't chew them as I used to do in my schoolboy days to the opprobrium of a number of teachers and my parents, as a result of which I took to cutting them as short as possible to kick the habit. This worked, but as a consequence I just can't stand to have fingernails that are long enough to do much useful except a bit of scratching from time to time.
So, as a result, I just cannot get the danged micro sd card out with my hands, I have to use a screwdriver or something. And then it always pops right out and sails in a graceful arc to land somewhere on my dark brown carpet, shiny side down. Did I mention I have weakish eye site?
So then after I retrieve it, plug it into the adapter for my regular SD slot, and plug the SD adapter into the slot mostly by feel then yes, the copy goes a lot faster. However then I have to extract it again, although I can (after a few tries) usually extract the micro sd card from the adapter with my hands, do you think I can just stick the thing back in the 800? Nope. I can push it in with my fingers but can't get it seated and it just pops back up. So I have to use the screwdriver tip again, and maybe half the time I still fail and the micro sd card does another graceful arc to the carpet.
So all in all, if you don't mind, I'll just copy my changes via the silly old usb cable. Then to the spare micro sd I keep in the computer slot as an extra backup. I worked in I.T. for twenty years and I DO my backups, believe me I do.
By the way I also have a GSP with a micro sd card slot, but Garmin have it set up so I can remove it with my fingers as they are rather easily. Maybe GRE could test their products with a few old folks when they do their next design with a micro sd card in it. The demographic is getting older and older and us old folks are gonna be a big part of the market for the next twenty or thirty years or so, and we're only gonna get even more grouchy.
