A third of the people who voted in last week's poll plans to buy a 5G phone in 2020. Another third are still prioritizing the other features on a phone, but are not against having a 5G-capable phone. Only the final third voted a firm "no". Among those, the most common explanation as to why not is that the carriers in their country are yet to launch their next-generation networks. In many regions this will not happen this year or even next year. This limits the value of 5G connectivity from the perspective of future-proofing one's purchase. It's much better to get an awesome camera now...
