To each their own obviously but I got my Milaana2 for pocket-ability. I love that I can slip into my front pocket. Although the Mi3 is being shelved at the moment, size would also be an important factor for me.
I use my splinter at home when I don't mind the bulk of the mod. Both are absolutely great but the Milaana seems to fill the gap in the lineup when it comes to size as compared to the splinter.
Is there a thread already started for the Seed? If there is a regulated device coming out, I will most likely get it. This all said, the US manufacturing for me was a bit of a draw but if performance is strong, that's something that can be overlooked. I personally like supporting domestic (Canada included) artisans. The RBT heater is phenomenal..only Tubo's heater can compare IMO.
Anything can be made portable. I can bring a log vape along for a car ride and plug it into the cigarette lighter if I want...doesn't mean that future versions of the log vape should be easier to carry.
If you want to take your milaana along with you for your day go nuts, but there are vapes made solely for the purpose of being small and "pocketable". They *might* make your travels easier.
I hope RBT goes by the old saying "If you try to please everyone, you'll end up pleasing no one." It sounds like they will though...
