I like it, and I don't mind paying extra for a sleek design with no push-button. that's just me though.
As far as vaping dry plant material - no, just fluids/oils and could probably do waxes good too.
I think, based on verbage provided in the HAUTEVAPE instruction manual, there likely will be other versions of the cumulus coming. Could one of those versions adapt dry plant vaping? - we'll see.
