HTC's announcement of a virtual reality headset, created in partnership with world-leading games company Valve (Half Life, Portal, Steam…), took Mobile World Congress entirely by surprise on Sunday.

HTC and Valve have hit a high note with the Vive Pre. It's a country mile ahead of the Oculus Rift in terms of interactivity and immersion and is simply stunning. We challenge anyone to try the Vive and not be impressed.

That about wraps things up here. We hope that answers some of the questions and curiosities that some of you might have had about the Lighthouse Tracking System. Feel free to discuss further in the comments below!

Before trying out the HTC Vive at GDC 2016, I signed an agreement that said I couldn't give you a full review of the system. I was told to avoid using strong language and to keep in mind that the demos I saw weren't the final versions.

Undoubtedly the best VR headset you can currently buy, but know its limits before you rush in

We've been waiting for the consumer version of HTC Vive – the company's virtual reality (VR) system – to land in our living rooms for some time. It's hard to describe the heightened feeling of excitement that accompanies the launch of a brand new technology, finally, onto the mass market.

Innovative VR that allows you to move around in a virtual space; excellent visuals thanks to high-res displays; controllers are excellent and offer developers many options for use

Setup is far from straight forward thanks to sensor placement; occasional crashes when installing; Room Space requires a large area to play in; headphones not built-in

I tested the HTC Vive Pre development hardware just last month, and now the final, consumer-ready version of the Vive is here. HTC's $799 virtual reality (VR) system is expensive, but it includes the works: a headset, motion controllers, and even external sensors for setting up a virtual room to...

Immersive experience; Includes motion controllers and external sensors for whole-room VR

Expensive; Tethered headset makes whole-room VR tricky

I took a walk through the future, and I want more. Instead of rooting you to a fixed point in your room and wrapping a 360-view around you, the $799 HTC Vive lets you stand up and explore it.

Room-tracking technology is eerily accurate; Smooth graphics with little latency; Touch controllers are easy to use and highly adaptable; Large library of games

Requires a lot of space and electrical outlets to use; No built-in audio; SteamVR Interface can be difficult to navigate

For the past five days, I've spent nearly as much time in virtual reality as real reality. My calves ache and my neck is sore, but all in all I've had a pretty good time. I've been using the Vive, an ambitious new virtual reality system created by HTC and Valve.

Virtual reality has always been an expensive hobby. Even in 1995, when the only VR option was the Nintendo Virtual Boy , it was hard to justify spending money on the device. It was uncomfortable to wear. It didn't have any good games. And it was a little ahead of its time.
