Hi Lyn!
How is using Calibre painful for you?
If you already know this I apologize, but just in case:
I use Calibre with my Pocket eDGe. The easiest thing, if you have Calibre on a computer, is to hook up your eDGe by USB cable to that computer. Once you have "mounted" the eDGe (pull down the notifications tab, tap notice, agree to mounting) Calibre (on your PC) will tell you it recognizes your enTourage eDGe. Then you can "send to device" and look at your eDGe library from within Calibre and all those good things.
Just don't forget to unmount when you're done.
You can also copy and paste from other computers on a network once you set your eDGe up to do that.
I'm so glad you got the basics up and running!
About the micro SD card: I have not tried using one, but I thought the smaller ones did not take over your storage, as allovertheglobe says, although the larger ones (larger in GBs) do. Check to be sure.
