Batteries are a pain in the arse, especially for gaming mice. But what if you charged your mouse through ... the mousepad?

Heading into CES 2017, we had a good idea as to some of the big trends we'd see. And we weren't totally wrong - Amazon's Alexa assistant was baked into gadgets everywhere, even in cars! But looking back at all of our coverage, there was plenty we had no idea about. This is the best stuff we saw at CES 2o17.

Last week Razer debuted Project Valerie, a cutting-edge laptop concept that switches automatically between one and three displays. On Sunday, two prototype models were stolen from the Razer booth at CES 2017. The company is offering $US25,000 ($33,960) for information leading to the arrest and conviction of those responsible.

Back when people still didn't know what the Switch was going to be, there was the Morphus X300. It looks awfully similar to the Switch, except that it plays Android games instead of Mario Kart. And as I found out at CES this year, it might actually end up in Australia one day.

Intel announced its Project Alloy VR concept back in August, but no one's been able to try it since. That all changed this week at CES, where Intel showed off a developer kit to select media. Gizmodo was lucky enough to be invited into the private demonstration -- and we're happy to report that it was well worth the wait.

Turning the Apple Watch on its side while it's charging overnight puts it in Nightstand Mode so you can always see the time. But with Elgato's amusing new W3 stand, instead of a tiny alarm clock, your Apple Watch becomes a miniature replica of the original Macintosh computer on your bedside table.

If you didn't catch Samsung's TV event and LG's press conference you might have missed it. The curved TV, once considered the whizzbang tech that would save televisions, is dead. Not quite in the ground, but no longer the darling of its makers. The curved TV is being quietly shuffled away from the limelight to make way for newer, and better, fads in televisions.

Finally: a monitor for the racers and space pilots among us.

It wasn't being demoed on the show floor when I went past, but we can still take heart in the knowledge that someone is giving coffee tables a bit of extra utility.

First it was Battle.net, and now it's NVIDIA. Take notice Twitch: the rivals are at the gates.

In front of thousands, the pitch sounded good. Bring PC gaming to the hundreds of millions who can't, or haven't experienced it before. It's a sensible, reasonable goal for a publicly listed company like NVIDIA to aim at. And the idea of putting a gaming PC in the cloud has a certain logic to it.

Problem is, we've been here before. It didn't work. And even if the streaming technology was sound, it still wouldn't work for Australians.

Not content with green glowing laptop keyboards, mice, headsets and capture cards, Razer has announced they'll be making your room glow soon enough as well.

It's too bad Razer already used the name Switchblade for its CES 2011 micro laptop concept, as it would have been perfect for Project Valerie, a gaming laptop that expands from one to three displays with the press of a button.

Press conferences are typically a dull, boring affair filled with speeches. Until Intel took (mostly) everyone into a room at CES 2017 and told them to put on an Oculus Rift headset.

There's an obsession with "immersion" in virtual reality. Everyone wants to find the next way to make VR experiences feel more real. So far, the best ways to do it have been room tracking sensors that let you walk around a designated area or wireless hand controllers that let you grab things in the virtual world. Now, a new startup is betting big on plastic shoes that give you a sensation that you're actually walking around in the virtual world.

As part of this year's CES shenanigans, the Formula E motorsport is holding a little esports event of their own. But while the electric division of Formula 1 branching into esports and sim racing isn't all that new, the prospect of them establishing a professional esports league is.

Look, we've been a little amped about Acer's absurd curved display laptop, the Predator 21-X. It's absolutely huge, but it's also a laptop with a 21-inch curved display and goddammit that is as cool as it is stupid. It is also, we've just learned, going to be very very expensive.

Shown as part of NVIDIA's keynote at CES 2017, the gameplay showed a good amount of Andromeda's UI, skill usage and how some of the combat would play out.

It can be difficult sometimes to get excited by the array of weird and wonderful technology on display at a massive convention like CES. And then you turn around and there's a speaker hovering in the air.
