Five years ago today, Apple introduced the iPhone. We haven’t quite seen a presentation like the one Steve Jobs gave that day before, we haven’t seen one since, and we may never see one on that same level again. Typically, we have a fairly good idea of what Apple will introduce. That day, we had no idea—and what they did introduce was so far beyond what we thought capable for mobile phones, it blew our minds, and shifted the entire mobile industry. And laid the foundation for the iPad, which is doing the same for computing generally.

Here’s a link to Apple’s video of the presentation. Here’s Ryan Block’s coverage of the presentation for Engadget.

I remember watching the keynote 5 years ago and though we know that it is something significant, the impact is not as clear as it is now, 5 years later.
