I have just installed Windows 7 on bootcamp, and I really like it. I do love Apple and OSX, but the software I would like to use most [Acad, Revit, 3DS Max] are all windows based...... Do I jump ship!!! Wish I didn't have these thoughts but MS has hit the nail with Windows 7 and is very tempting indeed. I wonder if Apple has some tricks up its sleeve to combat this one. BTW - I have been running my business on a mac for the last 3 years but still find it limited for design and architecture [I have vectorworks and have no interest in Archicad btw]. It is becoming frustrating a little bit!
