The first day of the International Consumer Electronic Show kicked off Tuesday and there was plenty to talk about.

But some of the headline stealers include drones, wearables and walkmans. Yes, walkmans.

The drones are coming

Drones are getting cooler, but they are also getting creepier.

At a keynote event Tuesday afternoon Intel CEO Brian Krzanich unveiled Nixie, a wristband that transforms into a selfie-snapping flying camera drone.

Krzanich also showed off the company's RealSense technology that enables autonomous flying drones to navigate around obstacles. For example, if you were walking towards the drone or tried to grab it, the drone would move out of the way. While the tech is definitely impressive, it's also starting to feel like drones may be getting a little too smart.

A chip to turn anything into a wearable

Intel didn't just show off drones on Tuesday.

The company also unveiled Curie, a button-sized system-on-a-chip that includes a processor and sensors that enable it to track activity among other things.

Basically, this computer-on-a-chip will make it easier for manufacturers to design and make low-power wearables. And because of its small size it can be integrated into a lot of different products including smart jewelry pieces like rings or connected buttons.

Wearables get normal

Speaking of wearables, there's a ton of them at CES this year and a lot of the devices are beginning to look less techy and more stylish.

The Walkman is back

Sony is bringing back the Walkman brand (Note: Millennials, this was before our time. See explanation here).

But instead of cassettes, this device will be all about playing different music file formats.

The Walkman's return though won't come cheap. The device is priced at about $1,200.
