Tommaso, many people here are disgusted by the unending Microsoft OS upgrading since Windows 95. Windows 7 is not even fully implemented now and we have Windows 8 forced upon us. Many here are now upgrading to Mac! I think Microsoft shot themselves in the foot, again. I work with Windows, but I am told Mac is so simple, even an architect can use it. 😊 (My son has Mac and loves it.) Tom, I would enjoy seeing some of your projects some time. I am fascinated by architechture.
