Milaanas are my portables. They can provide very solid hits. But they're not at the level of a nano. The other day I reached for my nano, always on at 6.2111, and it was a little less warm than it usually is (temps can vary slightly with mine due to where I keep it). I had what I thought to be a rather light hit based on the relative coolness of the heater and the vapor. But I was mistaken. It still did the trick. If I had to choose, a light hit on my nano would be preferable to a heavy hit on my milaana. And a full on lung splitter with the nano? I tend to be careful with how good a hit I take. When I first got my nano, which was my first and only desktop, I remember getting so stoned on a single hit that I'd find myself walking aimlessly around the house wondering what on the pale blue dot I was doing. My tolerance has risen a bit since then. But I seldom need or want two back-to-back hits on the nano. I start with one and come back for seconds and thirds etc. as desired on a hit-by-hit basis.
