Follow along as we find out what Tim Cook and company have been crafting in Cupertino

Steve Jobs Theater
The event this year started with a tribute to Steve Jobs, after whom the new theater is named.

Welcome to Apple's big day 2017. It's the day where we get to meet a bunch of new hardware, see some demonstrations, and have our Twitter timelines taken over by tech reporters posting pictures of other tech reporters waiting in line to get into the event. Not everyone can watch along in real time (or follow any of the many, many live blogs out there) so below you'll find a handy recap of the event with all the tasty bits of Apple info you desire. You can watch along with the livestream here.

Lots of talk about Apple Park and the Steve Jobs Theater to start the event. "Apple Park has been built to reflect Apple's values." There are lots of pretty images of the 175-acre campus. Powered by "100 percent renewable energy" with one of the world's largest on-site solar installations. There will also be an AR experience on campus to let visitors learn about what goes on there and how it works. Wonder how the meatloaf is in the cafeteria.

Apple Store experience
Apple sells stuff at their stores, but they want you to "hang out," there, too. Then, you can buy stuff.

Retail stores

Apple doesn't call their stores "stores" anymore. Now they're town squares. The stores are about more than selling with spaces for people to network learn, and yeah, buy stuff. Apple is touting its employees that it now considers creative pros. They're the artsy answer to the geniuses at the Genius Bar. They can also sell you Apple stuff.

Apple has big plans for retail. Huge stores in Chicago and Paris are coming soon. The New York store is getting redesigned too.

Apple Series 3
The new Apple Watch has cellular connectivity and now allows Siri to talk instead of making you look at your screen.

Apple Watch Series 3

With 50 percent growth year-over-year, the Apple Watch is now the most popular watch in the world and the newest version will have cellular built right into it. You get access to things like Siri and maps without having to drag your phone around. Apple Music is also now compatible with the Apple Watch.

The Series 3 will cost $399 with cellular built-in or $329 if you don't need that wireless connectivity option. It has a new dual-core processor inside that promises a 70 percent performance increase, but the Series 3 case is actually the same size as the Series 2. The new wireless chip inside is also new and promises increase efficiency.

The heartrate app is getting some upgrades. Now you can see your heart rate on the main screen. It's also getting into measuring recovery heart rate to get a better overall picture of fitness. It will also pay attention to your motion and compare it against your heart rate. So, when you're watching The Fast and the Furious, and you get amped, it'll let you know.

The Apple Heart Study is happening with Stanford Medicine using data from the built-in heart monitor. Apple is trying to get in on identifying irregular heartbeats like atrial fibrillation.

Apple Watch Series 3
The new Sport Loop strap will be for people with active lifestyles so try not to get Dorito crumbs on it.
Apple TV 4k
More resolution and HDR color for Apple's streaming box

Apple TV 4K

The aging Apple TV is getting a refresh with 4K resolution (which is four times the pixels as HD) and HDR color performance. It uses HDR 10 and Dolby Vision HDR tech, so it's compatible with the most common HDR protocols. Watching these 4K demos over a semi-crummy internet stream doesn't really translate.
