As some of you know, I am using the Ergo Pro as a vertical keyboard
https://geekhack.org/index.php?topic=79810.0 and travel with it. I was not 100% happy with the tablet bag I was using and found
http://www.actionlifemedia.com/bag-premier this is a perfect bag for the two halves (without the palm rests) and the rods ( 1/4" 3/8" spigot, "Triopo Short Column Ø24mm for MT-128 and GT-128 tripods", Manfrotto 259B Extension pole 6"-10", 1/4" male to 3/8" female screw) I am using. It's padded all around, has a padded separator between the two halves, there's extremely little space wasted -- just what the doctor prescribed.
