It's a great compromise. The story is about a specific family and that specific family is celebrating Christmas. But since Apple wants sell as many idevices as possible, they open up the message a little to everyone else at the end. Well played. An easy way to speak to more people with a touching story.
I partially feel this way, but let me tell you... after a weeklong road trip this summer, using Siri in the car... it was awkward at first, but by the third day, I had no trouble talking to Siri and asking for directions, sending text messages, looking up the nearest gas station. It didn't take long to make it feel completely natural. These shifts can happen so quickly.
I saw them changing the logo to red at the 5th Av cube last night. Unbelievable amount of effort to reach the apple. They built scaffolding from the sales floor around the spiral staircase that met in the middle high above the staircase. They had to cover all the glass handrails on the staircase with cardboard just in case a tool fell. All while the store was still open (5th av is open 24hrs)
