I'm not sure when Google will actually release the Linux version of SketchUp, but the Windows version beats AutoCAD very easily since the drawing methods are already in 3D and can be input with real world measurements. As for QuickBooks, well maybe Grisbi doesn't have as many Tax related features, but I sure love it far better than QuickBooks overall.
The only reason I still use Windows at work is for the benefit of MS Access...but that will soon change, when Hobo 1.3 is released. I believe that someday nearly all website design will be database centric and will be done with hobo and ruby on rails.
