Today, the tech world is on high notice as Apple begins it’s Wordwide Developers Conference (WWDC) in San Francisco, and is expected to introduce many new features regarding software updates ranging from iOS, to Mac OS X, to possibly, a new cloud service.Apple is extremely cautious this time around when it comes to keeping things under wraps, especially since the leak of the iPhone 4 caused Apple’s biggest embarrassment since the Apple Lisa. They seemed to have accomplished this difficult task, but things usually leak minutes before the event starts. The iCloud media service looks to be a sure thing, and the unveilings of Mac OS X Lion and iOS 5 are imminent. The things I’m most interested on is iOS 5 and iCloud. I can’t imagine that iOS 5 will just have a few adjustments, like a revamped notifications system. That wouldn’t be anything new, just different. Apple usually has the “wow” factor at these events and I think they have a hidden surprise that no one saw coming. Whether that will be iOS 5 or iCloud is anyone’s guess, but I’m hoping it’s for both. Make sure you go around the web for live blogs of the event. Mashable and CNET will be live blogging, and I’m sure all the Apple fan sites will as well. The WWDC keynote begins at 10AM PST (1PM Eastern Time).
