I hope this is a good thing as far as Graphisoft and ArchiCad are concerned! I also hope that Graphisoft has been expecting this. I really enjoy using OSX and ArchiCad. It would be good to hear a comment from Graphisoft of their thoughts.
I still prefer ArchiCad because of its flexibility regardless of the OS. I've used the other BIM program and it has some powerful features that I would like to see implemented in ArchiCad. Yet it doesn't top interactively working with the model to figure out, present and document the complexities of the design the way ArchiCad does. At the end of the day that is very important.
Since ArchiCad already seems to work faster in some respects on windows I would like to know if this change in processors and coding is going to further place the mac platform as 2nd string. Every other program I use I prefer using the mac equivilant. So, ArchiCad as my primary tool has to be top notch. I think that version 9.0 for mac has made great stides. Will it continue or lag behind it's Windows counterpart?
