The World Mobile Congress in Barcelona whirled around 5G technology -which won't be widely available until 2020- while it showcased the latest in mobile phones, foldable smartphones like the Samsung Galaxy S10, the Huawei Mate X or the Nokia 9 PureView -with more rear cameras than any other. But there were other gadgets on the Fira Gran Via floor: Microsoft presented its HoloLens 2, a light mixed reality headset only available for enterprises right now. The best camera zoom was the Oppo 10x and the biggest microSD card was the ScanDisk Extreme with 1TB of storage capacity. Huawei launched a faster and more powerful laptop, the MateBook X Pro (2019). The prices of these devices match their top-notch quality, as you can read in this link to Mashable, which opens the door to the technology you will be using in the future.
Although the Mashable report above is short and it illustrated with photos, the density of the information and the technical vocabulary makes this text a C1 reading task.
