The hottest tech at CES 2015 (Cnet)

1. A first for HomeKit. "Siri, brew a cup of coffee." iDevices released one of the firstHomeKit-compatible products, the Switch. The Bluetooth and Wi-Fi-enabled device lets anything plugged into it be controlled with Siri voice commands or through an app.

2. ZTE. What if you could upgrade your phone the way you could a PC? That's what ZTE, a leading Chinese phone maker, is showcasing. The Eco Mobius' parts can be swapped and upgraded by simply replacing its various modules.

And don't leave without testing ZTE's Star 2, an impressive voice-controlled smartphone.

3. Belkin. Charging ahead with home automation, Belkin is showcasing a new lineup of connected devices. Look out for a water-usage sensor, an alarm notifier, and even sensors for detecting when windows are opened.

Plus, take an early look at Belkin's Echo technology, a system of sensors that collectively analyze your utility usage.

4. Parrot. Camera-laden drones are an ongoing trend at Parrot, but this year, the company is also focusing on car tech. The RNB 6 lets you upgrade any car (including older models) with Android Auto or Apple CarPlay.

5. Intel Everywhere. Going beyond PCs, Intel is taking its investments to wearables. One of its focuses is on Quark, an SD card-shaped chip that can be plugged into a variety of wearable devices.

While you're here, check out the Lenovo LaVie Z, a 1.7-pound 13-inch laptop powered by Intel's new Broadwell chip, which significantly increases battery life and lets laptops go fan-free.

6. Streaming TV. Cord cutters, rejoice. Streaming TV is finally becoming a real option and Dish's $20-per-month SlingTV is a compelling example. The service works on Roku, Amazon Fire TV, LG Smart TVs, Xbox, and ESPN makes it shine.

But Dish isn't the only one in the game, keep an eye out for competing services likeSony's Playstation Vue.

7. LG. In 2015, 60 percent of LG's TV lineup will be in 4K, with a combination of both flat and curved screens. The new sets will run on the WebOS platform, a smart TV interface that can stream in 4K. For those who can't decide between curved and flat, there's even a 77-inch flexible concept TV.

And don't miss the G Flex 2, a curved smartphone that can withstand drops and pressure thanks to its flexible screen.

8. The connected car. While the real car showcase is in the North Hall, take a look at Panasonic's connected car setup. The company, which has a solid track record of building in-dash units, is now incorporating Apple CarPlay and Android Auto into its hardware.

9. Samsung. Curved screens are still plentiful at Samsung, where the company is now taking its flexible screens to desktop monitors. Bendy screens aside, the new focus is on Quantum Dots (also called nanocrystals), which allow even LED screens to appear brighter and more colorful.

Also take a look at Milk VR, a new virtual-reality game streaming service, along with a bevy of smart home appliances and a 105-inch bendable 4K TV.

10. Sony. As the company's lineup of 4K TVs expands, its also offering ways for consumers to create 4K content. Take a look at the various camcorders and action cams that shoot in 4K, and don't miss Sony's impressive 4K projector(available for a modest $9,999).
