I think everyone is already well aware that the delivery and release date is March 16th. No need to keep pointing that out.
As adults, many are trapped in jobs and schools with family obligations and stress and competing demands pulling at us from every direction. Christmas isn't even really a holiday for adults because of the stress of gift giving, travel, money, etc.
But a couple times a year, Apple releases a product that people preorder, and the delivery date is a day that is more akin to Christmas for a child. We digitally "peek" to see where our gift is, and hope and pray that we get it early, just like we did as children. This experience is arguably one that instills a child-like sense of wonder, anticipation and excitement.
For those of you who are more serious-minded and above all of this, that's fine. You're entitled. But for those of us who indulge our inner child once or twice a year, let us have that and all that it entails. This thread is a virtual space for people to share that. If you're not interested, don't participate. But don't sit in judgment and deride people who are just expressing joy and excitement.
