Having a big screen to write, read and view multimedia helped convince the world we needed larger displays.
In 2011, many smartphones stopped at 4-inch screens. The iPhone 4S was just 3.5 inches.
The original Galaxy Note wasn't just about the screen. It also introduced a digital stylus called the S Pen.
With it, you could navigate, write and draw all over the screen.
Samsung saw this device as a productivity tool, a message that that still rings true today for Galaxy Note phones.
For years, the Note has represented the best of the best in a given year.
Specs included a 1,280x800-pixel resolution for that 5.3-inch screen, and 16GB of internal memory, with up to 32GB in a microSD card slot.
The S Pen stylus slid into place -- today it clicks -- inside a hollow within the Note's body.
Notice the hook on the end of the stylus to keep everything in place.
The Note had a 1.5GHz dual-core processor and a 2,500mAh battery.
It shot photos with a 8-megapixel camera with flash, and a 2-megapixel front-facing camera.
Android 2.3 Gingerbread was already a generation behind, at launch.
The Galaxy Note sure has come a long way. Phones pack larger screens into ever-smaller bodies.
