WWDC 2007 was held in its usual home at Moscone Center West in San Francisco, California. It kicked off on Monday, June 11, at 10am PDT with a Steve Jobs keynote — the first since Apple previewed the original iPhone at Macworld some 6 months earlier. To say all eyes were on that state would be a profound understatement. The iPhone wasn't yet on the market and hadn't yet transformed the mobile industry, but its impact was already undeniable.
First up, Apple showed of OS X 10.5 Leopard. It would launch until later that fall — every resource possible at Apple was fixed on getting the iPhone out the door — but we did get to see a new Dock design complete with Stacks functionality, the translucent menu bar, Cover Flow in Finder, and Time Machine, which hoped to make backups effortless for the mainstream. There was also a new Automator, Back to My Mac to access your machines remotely, Quick Look, Spaces for virtual desktops, and more. What there wasn't was Classic Mode. It went the way of the dodo.
Safari, the browser for OS X and the iPhone got ported to Windows. It was probably more about getting WebKit onto Windows for use in iTunes and providing a way for Windows users to test web 2.0 apps on that rendering engine, and it didn't last long, but in that moment Apple doubled their cross-platform presence.
And then there were web apps, Apple's "sweet" developer solution. That it had been grueling, crushing work to get the iPhone to market, that no one at Apple had the time much less the energy to get an SDK done for OS 1.0, was the reality. But the demand was such that Apple simply couldn't ignore it. Unfortunately, web apps just wouldn't be enough and by the end of the year, Apple's iOS team would once again go through a marathon of sprints to get a native solution in place for the next spring.
Since Leopard wouldn't ship until much later, Safari for Windows wouldn't get very far, and web apps were quickly replaced with native apps, WWDC 2007 was more touch point than transformation. But it was Steve Jobs on the post-iPhone keynote stage, and that was something.
