I have a carrying case for my eGo Twist but its HUGE. I mean its the size of a PSP but the thing itself isnt that big. How do you carry yours around? Any suggestions on how to carry mine around? 
Mag-lite flashlight sheaths work great. If you are used to keeping your cell phone in your back pocket and taking it out before sitting down try the other pocket for your device, removing before sitting (great for larger devices like my Vamo or PV). Problem with front pockets (especially with tanks) is that the folcrum point on the device-heating element is normally in the same place as your hip joint and sitting or fast leg movement can easily snap them!!
