But is the Cosmos too little, too late to save HTC from irrelevance in the quickly changing VR market? The Cosmos is a good headset, with a higher resolution screen than both the Vive Pro and the Index, and it (finally) has ergonomic controllers, but ditching the Vive’s base stations in favor of inside-out tracking brought a host of tracking issues with the Cosmos....

An Intro to Facebook Lite As its name suggests, Facebook Lite is a lighter version of the standard app. It was designed for Android devices that can’t handle the bulkiness and power-sucking nature of the standard app. Facebook Lite has been stripped down specifically in size and system resource requirements so it uses less RAM, CPU and data. It can also run on unstable or low speed internet connections. Despite its ’lightness’ in system requirements and data use, Facebook Lite still offers almost all of the features you can get on the original Facebook app, meaning that you can still get the full Facebook experience even without the best device, data plan or Wi-Fi connection....
