I think the unboxing is a really, deeply emotional moment - you're meeting someone/something for the first time, who/what you expect to be your companion for years to come.
I realized this first when I've unboxed my first Mac, a Mac mini.
2005, East-Europe. Dormitory of a Software Engineering / Electric Engineering faculty, 12th floor. Macs were a distant technology, a unique thing of the strange West, the faraway US. Most of my roomates haven't even seen one before.
We stood around it.
It's a nice little box, around the size of 1000 sheets of A4 / Letter paper (a bit more close to the square, some 1:1.3 ratio).
Its sides are gray, bottom and top covers are white, in front, a mini, with the words written Mac Mini. Perhaps even a star, and denoting: actual size. It has a hinge.
First you remove the stickers on the top side (now front to you). You realize, that the ears of the paper is full 90 degrees, with a quarter-circle. Then you start to pull the top cover upwards. Again, you realize, that the ears are of maximal width for the front cover as well.
Inside, the polistyrol's corners are rounded, about an inch diameter. In the middle of it, there's a square hole. In that square hole, there's a gray square.
A single line of text is written on it, in a geometric font, set in plain white: Designed by Apple in California.
You remove the square - it's actually a small box, about a centimeter/half an inch deep, containing the CDs, the manual book (it's a BOOK! not a booklet), and two apple stickers.
Underneath, there is an apple logo, set in gray on shining white plastic.
That's the top of your first Mac.
Its technology is way outdated today, but I've never sold it. And I've never bought a PC ever since.
Grab an imaginary camera, shoot a point-of-view movie about the unboxing. How does it feel? How fast is it? Does anything - pneumatics, locks, stickers - slow it down? If they do, is it a kind of continous slowdown (like the pneumatics of an iPhone box) - or it feels more like an obstacle? Does it reveal anything? Does each of the stages of the sequence send a message about the product?
Path-Portal-Place. You go across something, you're to step into something (a new relationship), and then you're in it.
The order of the things, and the speed of the things are important. What you get to see first? How fast will you get there?
(It's actually a later edition with white sides, but it's still the same box overall)
This experience is designed. I'm pretty sure, a kind of storyboard exists somewhere either at Apple or at Frog Design or some other firm, where they have each of its stages as a comic.
So, Scott McCloud's classics (Making Comics and Understanding Comics), and movie storyboards are there to help you.
Edit: Here's a storyboard / animation for a nexus one unboxing. I don't know if it was for the product itself or wether it's fan art. But it shows the concepts: the order of the stages, the speed of the stages, and what gets the attention, what gets seen in each moment, what gets touched, felt, and what disturbs the attention.
