Yes that is true and can be said....this is primarily true because the difference is more operational in nature...... hardware is the same except for the boost button and user involvement....
I'm a bit surprised that you didn't like the 06 over the 05....yes it is true that they are basically the same except that the 06 can operationally be boosted which will afford the user the opportunity to better tailor their inhalation.... I sorta see it as recognizing the benefit of the FireFly but with a bit of a hybrid flare that Inhalater has become known for.....
The 06 can preheat things just below vaporizing so that.....when the user is ready to begin their draw they will play a very active role in creating their inhalation......ex:
1. how long you decide to depress the boost button - will either produce thin fluffy vapor or much longer likely creating thicker denser vapor
2. users at say a party might want to depress the booster for a period of time before they begin their draw - you might be looking to find a water defuse {bong}
3. now lets say your at the movies or some place were a much less detectable vapor is called for... a very short boost... with a nice long draw time - should produce very thin vapor
Yes those other things have also been addressed but it is operationally that will make you notice the main difference between them......IMO
I too have a couple 06's {his/hers} due to arrive next week sometime.... so I will be able to report if this boost feature is as awesome as it is supposed to be......
