The excitement has been mounting for weeks. Fans have speculated about the precise specifications of the device, the company behind it has been doing everything it can to preserve the mystery and build up the anticipation. Yes, Samsung has learned quite a lot from Apple about the art of hype.
I've been to several major gadget launches - the original iPhone, Sony's PlayStation 3, Microsoft's Xbox Kinect - and last night's unveiling of the Galaxy S3 smartphone in London's Earl's Court may well have been the most over the top and extravagant yet. In the cavernous halls where everyone from Pink Floyd to Madonna has strutted their stuff, thousands gathered to see a rectangular slab of plastic and metal.
Why? Because only one smartphone has challenged - perhaps surpassed - the iPhone in terms of sales, technology and consumer appeal. And the latest version will undoubtedly set the standard for Apple and the rest of the industry to try to match.
For all the extravagant talk of a device which allows you to "live the life extraordinary", the latest Galaxy looks at first sight like any other modern touchscreen phone. It does have a bigger sharper screen than its predecessor, and some clever touches. There's a voice recognition function which seemed in the demo to do everything that Apple's Siri does and more, there's eye-tracking technology which means that the phone goes to sleep when you stop looking at it, and there's NFC (Near Field Communication) built in, allowing users to simply tap each other's phones to share content.
But at its heart is the latest Ice Cream Sandwich version of the Android operating system - and that's on plenty of other impressive phones from the likes of HTC, LG and Sony. Why the new Galaxy matters is that the previous models have established it in consumer minds as the number one Android phone - and in this business, it's increasingly apparent that the winner takes all.
