Microsoft Windows 10 Devices Event: Everything You Need to Know

— -- Microsoft's jam-packed event in New York City today focused on new hardware that can be used with Windows 10.

Ten weeks after the software update, Microsoft said more than 110 million people have upgraded. The company then jumped into a two-hour briefing, showing off its latest devices designed for Windows 10, including new computers, smartphones and an update to its sensor-rich wearable, the Microsoft Band.

Here's a look at what you missed at the event today.

Surface Book

Microsoft's grand finale captured the most attention, so we'll give it to you first.

The software company released what it is calling its first-ever laptop, the Surface Book, a 13.5-inch screen with 6 million pixels.

"We have the best engineers who understand portability and performance," Panay said. "Ounce for ounce, pound for pound, this is the fastest 13-inch laptop ever made."

Panay said Surface Book is twice as powerful as the MacBook Pro.

It features a 12-hour battery life, company officials said. It starts at $1,499 and will be available Oct. 26.

It weighs 1.6 pounds and is 7.7 mm thin. It's essentially a clipboard, making it easy to show someone something on your screen.

Surface Pro 4

Microsoft has continued to up its game when it comes to making devices that function as both tablets and laptops.

The Microsoft Surface Pro 4 made its debut today, boasting a 12.3-inch screen with 5 million pixels, making the resolution even higher with an even thinner screen.

The release of the Surface Pro 4 comes as Apple and Google recently unveiled their latest entries into the 2-in-1 device category, with the iPad Pro and the Google Pixel C.

The Surface Pro 4 starts at $899, and will be available Oct. 26. It also comes with new accessories that will work with the Surface Pro 3 as well, including a docking port and a new light touch keyboard complete with a finger print sensor, letting power users take advantage of the biometric security in Windows 10.

New Flagship Smartphones

Microsoft's Lumia 950 has a 5.2-inch screen while the Lumia 950 XL will appeal to large phone lovers with its 5.7-inch screen.

"This is supposed to be the most productive phone you've ever picked up," Panos Panay, head of devices at Microsoft, told the crowd. A demonstration showed how continuum, a feature from Windows 10, allowed users to seamlessly shift between their computer screens and their Lumia smartphone.

Windows Hello, which works with an iris scanner to recognize a device's user and instantly unlock it, is available in beta for the new phones.

Microsoft's new phones also come with a sharp camera and a fifth-generation optical image stabilization system making it perfect for smartphone photographers.

"I don't care if the image is moving or I'm moving, it's going to be clear," Panay said.

Both devices use the USB-C charging standard and include up to 32 GB of internal storage. They'll be available beginning next month, with the Lumia 950 starting at $549 and the Lumia 950 XL starting at $649.

Microsoft Band Gets Even More Features

Microsoft's first wearable, the Microsoft Band, has stood out as a sensor-rich device for tracking everything from sleep, heart rate and activity to keeping up with messages and calendar events throughout the day. Now, the company is ready to bring the Band into the world of Windows 10.

The software company showed off the newest Microsoft Band today. The latest version of the Band includes an 11th sensor -- a barometer -- allowing wearers to track their elevation. It also includes more integration of Cortana -- Microsoft's digital virtual assistant -- along with a curved screen with extra tough Gorilla Glass. Microsoft Health, the dashboard letting Band wearers see their data, will also now including readings for VO2 Max, a key metric for fitness buffs looking to measure their maximum oxygen intake.

Pre-orders for the new Band begin today and will be available Oct. 30 for $249.

HoloLens

The mixed reality headset will be available to developers beginning early next year starting at a price of $3,000.
