The evolution of Apple gadgets

First released in June 2007, the original iPhone revolutionized technology. But it wasn't Apple's first major gadget. Here's a visual trip through Apple's many gadget hits and misses.

Let's start with Apple's inaugural mobile device, the Newton MessagePad, first developed in 1993.

The personal digital assistant was the first hardware to feature handwriting recognition, but the ahead-of-its-time innovation was discontinued in 1998.

Introduced in 2001, the first-generation iPod revolutionized music consumption. The hardware included a black-and-white LCD screen and a 5GB hard drive that could store up to 1,000 songs.

Not every iPod was a hit, though.

Introduced in 2004, the U2 special edition black iPod came equipped with an eye-friendly red click wheel... and a price tag $50 higher than the original model.

Sales were so poor that the flop is now a collector's item fetching tens of thousands of dollars.

Unveiled in 2004 -- along with the U2 Special Edition iPod -- the iPod Photo is an upgraded version of the fourth-generation device. This iPod supported several photo types and it could be attached to a TV.

Released in February 2004, the iPod Mini featured the same touch-sensitive scroll that the third-generation iPod had. The difference in the device -- other than being smaller -- was the click wheel.

The iPod Mini was discontinued in 2005.

The smallest iPod model, and the first Apple device to use flash memory, was released in January 2005. The shuffle played random songs that were previously loaded by the user.

Coming off the iPod Photo, Apple introduced the fifth-generation iPod a year later. This upgraded version was the first Apple digital audio device that could play video. This is also the last iPod model to use a glass face.

In 2005, Apple decided to replace the iPod Mini with the Nano. The tiny device, equipped with a color screen, stored music with flash memory. The first-generation Nano had a battery life of up to 14 hours.

After years of rumors, Apple finally announced their first smartphone in January 2007. As Steve Jobs put it at the unveiling of the smartphone in 2007, the iPhone is a combination of a "widescreen iPod with touch controls", a "revolutionary mobile phone" and a "breakthrough internet communicator."

Timemagazine named it the Invention of the Year.

Released the same year as the first-gen iPhone, the iPod Touch is similar to the smartphone except it's lighter, cheaper and doesn't use a cellular network.

With a design that mirrored the iPod Classic, the third-generation Nano was the first model of the device to allow video playback. The iPod Nano came in multiple colors and two storage sizes, 4 and 8GB.

Unveiled as "iTV" in 2006, the first-generation Apple TV, a digital media player, needed an iTunes connection to work. The following year, Apple released a major update that turned it into a standalone device.

In July 2008, Apple's second-gen iPhone 3G was released with a multitude of upgraded features. The improved hardware included a sleek and sturdy design, an improved battery and a rear camera.

Nearly two decades after releasing the Newton MessagePad, Apple re-entered the tablet game with the iPad, a 9.7-inch touchscreen display.

After just 80 days on the market, Apple sold 3 million iPads.
