 Every year, more than 6,000 developers flock to San Francisco for Apple's Worldwide Developer Conference, which gives them their first look at all of the new features Apple is bringing to its increasing number of operating systems. iOS for mobile devices, OS X for the desktop, and now, watchOS. Welcome to WWDC 2015. This developer conference continues to be the epicenter of change for not only Apple, but the industry. First big thing Apple announced today, iOS 10 El Capitan, the next version of their desktop operating system. This is a very incremental release. They emphasized improved graphics performance. There are some new ways to manage Windows a little bit more easily, and there's going to be various new gestures for managing your mail, things like that. Some people are going to look at this and say it's kind of boring, but me personally, I'm okay with the operating system taking a year to just get really stable, get a little bit faster, work on the graphics performance, and not worry about introducing some major new feature. So El Capitan is going to roll out as a free upgrade in the fall. It's not going to change your world, but it is going to make things just a little bit nicer. iOS 9, another fairly incremental release for Apple, although it does come with a handful of big new features. One of them is called Proactive, a new kind of Siri that will attempt to anticipate your needs without you having to do anything. So swipe to the right and you'll see people you often talk with, you'll see apps that you often use, and it will try to kind of help you get where you're going without you having to do as much as you used to before. Another big feature in iOS 9 that's interesting, if you have an iPad, you can now do split screen. So you could say work on a document in most of the screen and then have Twitter running on the right hand side, or you could have a web browser open with a picture in picture video of something that you're watching on Netflix. If you have an iPad, I have a feeling this is something you're going to be using a lot. Apple also showed off News, a news reader that will remind you a lot of Flipboard. You tell it your interests and the publications you like, and it will organize all of those together in one place. Still a lot of questions about this as we're heading outside the event. Is Apple splitting revenue with publishers? How exactly is that going to work? I don't know. Generally speaking, I'm pretty down on these kinds of apps, but Apple says they found a way to make reading beautiful on iPad and iPhones, and that's going to be coming out shortly. The third thing Apple talked about today was WatchOS, which is of course the operating system for the Apple Watch, which just came out. And the big news here is that starting soon, developers are going to be able to write apps natively for the Watch, whereas before you used to have to route everything through an iPhone. So now developers can build brand new experiences just for the Watch, and you should start seeing those roll into the App Store shortly. The last big thing Apple talked about today, Apple Music. It's long-awaited Spotify competitor. You pay Apple $10 a month. You can stream anything you want on demand without any ads. It also comes with a global radio station called Beats 1 that streams 24-7, and a service called Connect that will contain extras from your favorite artists like lyrics or song demos. There's a lot in there. I want to get my hands on it and play with it. It didn't blow me away, but it does have a really cool integration with Siri, so you can just activate Siri, tell it what you want to hear. It'll start playing immediately. The big theme of today was incremental improvement. We saw lots of things that are getting a little bit better. Some people are going to say that's boring. I actually think it's great. This is how software improves over time. At the end of the day, I saw a lot of stuff that I can't wait to get my hands on.
