So, in essence, we are talking mostly about changing the electronics a bit and instread of a tubular coil, the polyimide tube will be surrounded by flatter heating elements (flatter coil?). Doesn't better heat distribution mean faster vaporization of the load inside? Quicker reacting temperature sensing means it will start blinking (heating) faster and it will stop heating faster as far as I can understand. So, these changes point to a device that might have better battery life (but not by much), maybe even more/faster vapor production (as if it wasn't plenty/fast enough) and an elevated sense of honesty as to what it shows to it's user.
If I am right, I won't feel stupid when the XP hits the shelves. If there is more under the hood, I will just load some more capsules to forget and let the time heal my feelings...
