Technological innovation has its downside. Try and attach our old fitness band to our new smartphone and we might find the Bluetooth protocol it uses to communicate is no longer supported, or the servers they used to run were attacked and taken down by hackers.
Backers of the original smartwatch, The Pebble, found themselves on the wrong end of this situation when the company was bought by Fitbit, who decided to shut down the Pebble servers. This effectively turned all Pebble watches into paperweights, although an unofficial fix was developed.
Assuming the hardware works, we might find the network connection deserts us.
Last year, the WiFi Alliance announced a new WiFi standard, increasing speeds for countries that support it.
But it’s already the case that older WiFi devices running on older standards can have trouble connecting to new networks, and even if they can, they are likely to slow down the whole network.
