Apple has just sent out a press release announcing their 2011 Worldwide Developers Conference. It will occur June 6-10 in San Francisco and will "unveil the future of iOS and Mac OS". There will be technical sessions and app demonstrations, but no new hardware is expected to make an appearance. What we can expect to see are more signs of the growing convergence between iOS and OS X.
Last October we saw FaceTime for Mac go live, along with a new version of iPhoto that looked nearly identical to the iPad Photos app. The Mac App Store also launched. For the last year, iOS and OS X have been growing closer together.
And OS X Lion promises to take this integration a step further. First off, Apple's adding in an Ultimate Remote Desktop feature. This will make sharing files between your Macs easier- and we may see iOS gain something similar. The ability to stream files from your local network and even access desktop applications would make the "living room iPad" much more convenient and productive.
Lion will also have disappearing scroll bars to increase screen real-estate. This change will bring the browsing experience on both Macs and iOS devices closer together. Which seems to be a big part of Apple's Master Plan.
Macs will always need to be more robust machines than a limited mobile device like the iPhone. But people seem to prefer browsing and exploring media content on handheld devices. Apple can't (and doesn't want to) totally replicate the mobile experience on a personal computer. But they can bring both platforms more in line, so the end-user notices less differences when carrying out his day-to-day computing tasks.
