I think I'd like having them as different platforms. The Cera eo I want as my go to, but I may treat it as a home device. My state just went medical today, so I do not have any sort of medical card. But the cera is the medical device, any herb attachment would be more so recreational.
What I'm thinking I could do is carry the evo for casual use with a Rev cartridge for emergencies in the car, and leave the cera at home for safe keeping until I can have some more claim to it as a medical device. But, the ll looks awesome, and the much longer battery life is pretty awesome, so...
And 2clicker, I may have to give you your advice back and tell you to get the EO cart, it looks like it can REALLY produce clouds, if that's your thing.
