Oculus Rift

รูปภาพ
Update (3.1.17): Oculus Rift is getting a massive price drop in the US. Announced at GDC 2017 , the hardware will now be sold in a package deal with the Oculus Touch controllers for $599. Separately, you can now by the Oculus Rift headset for $499, and the Touch controllers for $99. That makes it about $200 than its closest competitor, the HTC Vive, and a pretty good deal for gamers just getting into VR. It's tough being the trailblazer, especially when it comes to technology, and the Oculus Rift has felt that more than anyone else.  It was the product that kicked off the virtual reality craze and got the world interested the new medium, but after its announcement other competitors came to market with a more complete vision, with motion controllers included in the box and other technological advantages.  When we first reviewed the Oculus Rift it was still having teething problems, but now, after the release of its own (very capable) motion-controllers in the form of the Oculus Tou...

Panasonic Lumix FZ2500 / FZ2000

รูปภาพ
Panasonic has long offered a respectable range of superzoom cameras within its Lumix portfolio, but the Lumix FZ1000 was still a notable addition when it arrived three years ago. The reason? While it adhered to the same formula as previous FZ models, by employing a 1.0-inch-type sensor it promised far better image quality than we'd expect from such a camera. This, combined with its DSLR-style body, meant it became a natural rival to the Sony Cyber-shot RX10 , a camera that also married a long zoom with the same size of sensor. Sony has since updated its camera twice, most recently with the Sony RX10 III , while Canon has also muscled in on the action with its 1.0-inch-sensor-toting PowerShot G3 X . Now, Panasonic is fighting back with the FZ2500 (it's called the FZ2000 outside the US). The new model arrives with a longer lens than its predecessor's, together with a handful of updated features, and the FZ1000's video specs sweetened with a few extra additions. Indee...

Apple TV

รูปภาพ
Update : A new report suggests that a 4K Apple TV box is finally in the works –   read more about it here. Apple TV review continues below... If it existed in a bubble, the revamped 2015 Apple TV would be a stellar product. It offers a steady improvement over its three-year-stagnant predecessor - a device built for the then revolutionary new standard of 1080p - and comes with one of the most premium remotes on the market. If there was nothing to compare it to, it'd be hard to point out the number of flaws the system has. It's lacking the majority of Australian streaming apps, for example, and Siri recognises less than half the commands on the new Apple TV than it does on iOS, watchOS or OSX. The situation is improving. At WWDC 2016 Apple noted that 1,300 video channels have now made it to the device alongside 6,000 native apps. That's not to mention the fact Siri is voiceless at the moment, relying on text and graphics to respond to any inquiries you might have. Siri has h...
