These days my go-to example of "you cannot bet on having access to better technology as time progresses" is "I used to have an app on my phone that could predict the next hour of weather with startling accuracy and that is no longer an option"

(I am talking about Dark Sky)

Edited to add: I only want to hear suggestions for services/sites/apps if they offer the same ~10min interval microforecasts for the upcoming hour that Dark Sky used to, because that is the thing I am lamenting
