As a current Rhino 4 owner and having played with beta 5 while also having MoI my question is.....

How many Rhino users have ran into many instances in which Rhino was needed to finish a model as opposed to Rhino being used as a habit?

I am able to upgrade for around $350 to Rhino 5 and I almost did it but I was also thinking that I might upgrade with blinders on. Knowing that there are times that I still prefer using feature / history based CAD tools I find that MoI, when I force myself not to rely on CAD, does the work.

So, those of you that use MoI and Rhino, are you going to upgrade Rhino to 5 out of need or convenience (or just being used to Rhino).

Michael Gibson - since you clearly are quite knowledgeable in both Rhino and MoI maybe you can also chime in and hit the areas that maybe are not obvious to most people. I would hate to overlook a cool feature, like import/export options of Rhino that I rarely use.

Any feedback is great.
