No problems with CAD on a Mac, TurboCAD is just one example of available software... the only one that isn't available is AutoCAD. Photoshop, no problem there... Adobe made photoshop on Mac long before it made it for PC. Photoshop, illustrator, indesign, dreamweaver, flash... anything... all available. HD video? Don't have a problem with that either. Plenty of apps you can put on a pc, plenty of apps you can put on a mac... Games, refer to my previous post regarding consoles. Although, the gaming situation is improving rapidly.
