2003 was a big year for Apple, headlined by a preview of the PowerMac G5. What was then dubbed "the world's fastest personal computer" was the first Mac to sport a 64-bit processor. The machine went on sale two months later, and started at $1,999. Apple still uses a very similar design in its current Mac Pro tower, making it one of Apple's longest-lasting looks.
Also announced: A preview of OS X 10.3 "Panther," Safari 1.0, Xcode, and the iSight camera and iChat software.
Alongside its preview of OS X 10.4 "Tiger" in 2004, Apple broke out a new trio of flat-panel displays. The biggest of the bunch was a 30-inch, 2,560x1,600-pixel display that cost a whopping $3,299. To run it, users needed an Nvidia GeForce 6800 Ultra DDL graphics card (an extra $599) and Apple's PowerMac G5 desktop tower.
Also announced: Xcode 2 and OS X 10.4 Tiger for servers.
2006's show brought the Mac Pro, a new version of the old PowerMac machines that was now running on Intel's chips. It wasn't the first Mac to go from PowerPC chips to Intel, but it was certainly the beefiest. The first model cost $2,499 -- the same price as it costs today.
Also announced: A preview of OS X 10.5 "Leopard" and its Xserve quad-core server.
While Apple was lagging on getting OS X 10.5 Leopard done, and working behind the scenes on a real software development kit for the iPhone, the one thing most people came away with from WWDC in 2007 was a version of Safari for Windows. The public beta of the software ended up getting downloaded more than a million times the first two days it was out.
The biggest knock of the original iPhone was that it didn't have 3G, when many other smartphones on the market did. Apple debuted the 3G model at WWDC 2008 and went through a number of demos to show how much faster it was than its old phone, and even compared it to some rival phones too.
Apple also debuted MobileMe, its sync and Web subscription service, which ended up having numerous problems and became an embarrassment to the company. Apple ended up killing it off in 2011 with iCloud.
Also announced: iOS 2.0 and a preview of OS X 10.6 Snow Leopard.
WWDC 2009 was full of hardware and software, but the biggest bit came with the introduction of the iPhone 3GS. This was Apple's first "S" model of an iPhone. Its big claim to fame was that it could finally shoot video thanks to a faster processor. Apple also announced iOS 3.0 (then called "iPhone OS") which finally added cut and paste and voice search -- the precursor to Siri.
Also announced: A new 13-inch MacBook Pro along with upgrades to Apple's 15- and 17-inch models, Safari 4, and a demo of OS X 10.6 "Snow Leopard."
"Stop me if you've seen this before," Apple CEO Steve Jobs quipped while showing off the iPhone 4 to a packed room of developers. A full two months before WWDC 2010, gadget blog Gizmodo had gotten its hands on the device and posted photos and even videos of the hardware on the Internet -- an acquisition that would later lead to a criminal investigation and a very public embarrassment of an Apple engineer who had left the prototype of the device at a bar.
The rest is history, of course. The iPhone 4 went on to become a best-seller, and the general design for the next two generations of iPhones.
Also announced: Apple's iAds platform, Safari 5, Apple's FaceTime video chat service, and iMovie for iOS.
Apple's 2011 WWDC brought iCloud, a total redo of MobileMe. iCloud did many of the things MobileMe did, but for free. Steve Jobs explained it as a sort of glue that tied devices together, and took over many of the tasks that people were using computers to do with their mobile devices.
Also announced: Price and release date for OS X 10.7 Lion, and a preview of iOS 5.
The 2012 WWDC brought a bunch of Mac hardware revamps, but none were as dramatic as Apple's new high-end MacBook Pro. Its big claim to fame was a new "Retina Display" screen where the pixels were so tightly packed, you wouldn't be able to make them out while using the machine. It also completely did away with a disc drive, and even hard drive -- making it more like a MacBook Air. Apple offered up that it was the "next generation" of its notebooks.
Also announced: New models of the MacBook Air and MacBook Pro with speedier processors and some new features like USB 3.0, along with a preview of iOS 6 (which would bring Apple's mapping service), and a price and release estimate for OS X 10.8 "Mountain Lion"
Though it had added many new features since the very first iPhone, the design of iOS had barely evolved in those six years. That changed with iOS 7, and in a big way. The "flatter" visual overhaul transformed everything,
from the typography and color schemes to the typical
icon and button shape across the entire platform. Oh, and new features came, as well, like a Control Center, AirDrop, and automatic app updates.
