Powerful phones, VR dominate at Mobile World Congress

Facebook's CEO Mark Zuckerberg took the stage at Samsung's press conference to talk about Facebook's plans to make virtual reality more social. Maybe one day we'll browse our New Feeds from a headset.

Check out everything Samsung announced at MWC.

LG's smorgasbord

LG brought a lot to MWC this year, including a VR headset and a brand-new phone, the G5. What makes the G5 so special is that you can swap out the battery and replace it with accessories such as the LG Cam Plus, a camera grip and shutter accessory that also adds more power. The LG G5 is somewhat of a modular phone, like Google's Project Ara phone, and it's first of its kind that we've seen that will actually be sold around the world.

LG also showed off the Stylus 2, a phone meant to rival Samsung's Note line with its own stylus. It ships with Android 6.0 Marshmallow and has a 5.7-inch screen.

For the home, LG created the Rolling Bot, a security camera, smart home device and pet toy in one. It can keep an eye on your home, turn on the lights for you and entertain your puppy or cat while you're away.

Lastly, LG is getting into the VR game with its own headset, the LG 360 VR. It's much smaller than other headsets we've seen and it plugs into your phone, instead of you putting your phone inside.

The HTC Vive has a price, and there's a new HTC phone

HTC's virtual reality headset known as the Vive goes on sale this April for \\$799 (?689, roughly AU\\$1,115), HTC and gaming company Valve confirmed on Sunday. That's \\$200 more than the rival Oculus Rift VR headset.

HTC also announced the One X9 for the US. The striking all metal phone has been available only in China until now.

HP's new phone is a computer too

Following in the footsteps of Microsoft's Lumia 950, HP's Elite x3 phone can be used as a computer too with the help of a dock. It's running Windows 10 and can plug into a monitor so you can use it as a full-functioning Windows computer. Unplug it, and it's a phone again.

Projectors all around

Tiny projects are a thing now, designed to slip into your pocket and set on a table for a presentation. ZTE announced the Spro Plus, an Android-powered projector that uses lasers instead of LEDs. Oh, and it has a JBL sound system too, so you can watch movies or TV with it.

There's also the Akyumen Holofone, a Windows phone with a built-in projector. It's not the coolest-looking phone, but it's practical, and the company is selling both a consumer version for all of us and an educational version for classrooms.

Lenovo's budget tablets and versatile laptops

At MWC, Lenovo introduced three new tablets, all with the option for LTE and all under \\$200 (or roughly ?140 in the UK and AU\\$280).

The company also introduced smaller Yoga laptops. There's a new 11-inch model of the Yoga 710 that uses Intel's Core M line of low-power processors, plus 8GB of RAM and up to a 256GB SSD. Meanwhile, the Yoga 510 gets a makeover with a new streamlined design. Called the Flex 4 in the US, the laptop flips all the way around like the high-end Yoga models, but with a more budget-friendly price.
