Sketchup? meow? most architects are moving to parametric style architecture. it is much easier to work with then traditional CAD systems. with CAD, if one architect down the line has to change the window in a facade, say 1 cm, then the entire drawings from all perspectives would need to be changed individually. with parametric software (i believe Zaha Hadid's office uses rhino) these changes happen instantly. afaik, rhino runs in WinXP only. i have worked in several major architecture offices (OMA, Zaha Hadid architects, etc.) and NO ONE uses a mac, other then the IT department. all the architects in major architectural offices use winXP.
