Speaking only for myself, a pod system will have a negative impact for any of us with hand/finger dexterity issues. The current method to load material is very easy with the only real drawback being the issue of load material falling into the heating chamber or heater screen. The use of double screens eliminates this problem, but does introduce other issues which are a catch-22. With all convection vaporizers the major issue is getting an ABV that is even and consistent as the ABV of the better conduction type vaporizers. Since hydraulic power is the engine that drives convection vaporizers the challenge is to distribute the heat used for vapor production to be applied as evenly as possible. Currently all the convection vaporizers I know of pull the heat through the load from bottom to top, and this is the main reason the load needs to be stirred. Of course you could crank up the temperature but the degradation of vapor quality is the trade off. You could also slow the draw speed through the load but it will still impact vapor quality negatively. Convection heating demands the heat to be distributed equally to all surfaces of the material to be heated, if it isn't some of the material will be charred while some will be almost untouched. This is the reason convection cooking ovens have fans to circulate air flow. Anyway, I think whoever designs a convection vaporizer that pulls the heat through the load from outside to inside or vice versa rather than from the bottom to the top will have the ideal vaporizer. It would produce even ABV, allow a lower temperature to produce vapor, preserve the vapor quality, and up the efficiency. My thinking might be all wet, but I just cannot see a vaporizer pulling heat vertically through loaded material ever being able to heat the material evenly when the basic rule of hydraulics is to always take the path of least resistance, i.e. the reason why, so often, the load will be charred in the middle if the draw speed is to fast. Sorry for the length of this post and my meandering
