I have been using the Mac Book Pro for a week now and am still very impressed with this machine. It is quiet small light and very fast. I have no noise and no disk problems, I was told to by a service tech to stay away from reconditioned machines. The only problems that I am having are software. The only sofware that I use that I have a problem with is Vectorworks (I have used Word, Excel, and Photoshop this week enough to feel comfident with them). Vectorworks seems to work fine and fast except for the items on the list. In addition to that windows PIO is broken it is not just muntin size, the sash often appears above the frame etc. When I phoned tech support they told me that the window PIO worked except for muntin sizes. However once the file is reopened with the G5 the window opened with the imfo pallet and settings are clicked it will fix it self. Conversely if you click on a window symbol of a window PIO and open the settings pallet on the Mac Book Pro the sash will move up, if you undo it will be fixed. You can move window PIOs replace window PIOs etc. just don't open the setting box. The other issues on the VW tech are less important for me. Can we get a patch for the window plug in before the release of v 12.5?
