Observations• iPad / iPhone dev is simple yet unique
• Portrait to Landscape transitions take effort
• Distinct view classes can be created for iPhone and iPad within an app
• Objective C notation has its own style
imageView = [ [ UIImageView alloc ] initWithImage: [ UIImage imageNamed: @"Map.png" ] ];
• Memory management is required
[ imageView release];
