The iPhone has become such a major part of our existence, a piece of technology that we almost take for granted, that it’s difficult to remember a time when we were instead tapping away at our Moto Q, Palm Treo and Nokia E62 handsets.

But while the iPhone has gone on to revolutionize our lives (and Apple’s business) it’s not that long ago — eight years today — that Steve Jobs stood on stage at MacWorld 2007, and told the world that Apple had created a touchscreen iPod, a cell phone, and a breakthrough Internet device all-in-one.

Coming off its most profitable holiday season ever, and a record-breaking week for the App Store, it’s worth taking a moment to rewatch Jobs’ first iPhone presentation: both to see an iconic moment in tech history, and to be reminded of how far we’ve come since then!

Happy birthday, iPhone!
