-- If your head is still spinning from the Apple event on Tuesday, you're not the only one.
In the span of two hours, Apple unveiled two new iPhones, a smartwatch, an operating system update and an electronic wallet that may soon make plastic credit cards a relic of the past.
It was exciting -- and also a lot to take in. Here are five of the most frequently asked questions from the event. If you have one we haven't covered, let us know in the comments.
When can you get the iPhone 6 and iPhone 6 Plus?
Tim Cook called them the best iPhones Apple has ever produced, but you can't get one just yet. Pre-orders start on Sept. 12 and the first units will ship on Sept. 19.
The iPhone 6 starts at $199 for a 16 GB configuration, $299 for 64 GB and $399 for a whopping 128 GB configuration, with a two-year contract.
The iPhone 6 Plus starts at $299 (16 GB), $399 (64 GB) and $499 (128 GB). Both phones come in three colors: gold, silver and space gray.
What's the battery life of the Apple Watch?
While the Apple Watch excited with its style and functionality, one of the lingering questions is whether its battery life will be enough to entice buyers.
Apple has not revealed the battery life of the watch, which is slated to come out in early 2015, however CEO Tim Cook's comment that you can charge the watch at night while you sleep has led many to speculate that the watch will need to be recharged every day. While declining to provide an estimate on expected battery life, Apple spokeswoman Nat Kerris told tech news website Re/code that the company expects users will charge their Apple Watches once daily.
What we do know is how to charge the Apple Watch. It will include MagSafe technology with inductive charging, meaning all users have to do is hold the connector near the back of the watch and snap it into place.
Apple says it's so easy that it can be done even after you've already turned out the lights for bedtime.
Is it necessary to have an iPhone if you buy the Apple Watch?
Yes. Apple Watch, which starts at $349, will be available in early 2015. The watch requires iPhone models 5 and newer.
What are the security features of Apple Pay?
Apple is asking consumers to trust them with a digital wallet called Apple Pay. Tim Cook told ABC News in an exclusive interview with "World News" anchor David Muir that the product is "incredibly safe."
Apple uses a new chip called the Secure Element, which is embedded in the new devices. The chip stores users' encrypted payment information and allows them to pay for items with a simple swipe.
"I feel incredibly certain that it’s very secure -- the most secure thing out there," Cook said.
At the event on Tuesday, Eddy Cue, Apple's senior vice president of Internet software and services, said users can add a new card by taking a photo of it, getting it verified at their bank, which then adds it to Passbook.
Payments can then be made with a simple touch of the device at payment points, which will be in some of the most popular stores in the United States.
"Apple doesn't know what you bought, where you bought it or how much you paid for it," Cue said.
I have an iPhone 4. What does this all mean for me?
Here's the not so great news: The shiny new iOS update will only be compatible with the iPhone 4S and later models.
Apple's iOS 8 is being hailed as the biggest operating system release ever because it comes with updates to popular apps, such as messages, photos and the keyboard. The operating system update will be released on Sept. 17 -- two days before the new iPhones go on sale.
While you won't be able to update your phone or take advantage of the latest and greatest apps, there is still some good news for iPhone 4 users who are ready for something new but don't want to shell out on the iPhone 6.
The iPhone 5C is being given away for free by many carriers, along with certain contract commitments. You heard right. Free.
