Ok, these are all reasons to upgrade, but that wasn't the question.
The question is, why couldn't you wait 4 or 5 more days for these things?
Your list of reasons is consists entirely of "I could do x before, but now I can do x faster/better/nicer."
My reaons for standing in line is that "I can now do x, y, z, and a, b, c, and d now whereas before I couldn't do them at all."
I can see waiting 4 hours in line to gain a ton of new features. I can't see waiting 4 hours to get a faster/better version of what I already have. Why not just go this Wednesday?
That's the question, and nothing in your post addresses that.
