Hi, someone mentioned a couple of days ago on here about a bookcourier case from reading machines. I had a couple of questions about it. Is this just a carrying case to hold your bookcourier when traveling. Or is it meant to be used and always kept in the case. I guess what I'm asking is are all the ports accessible from the case. Personally I really don't care about this feature as much, but I'm just wondering what exactly it would be used for. Thanks for your help. Holly
