Yeah, this is a really nice feature; on the couple of rare occasions where an update completely borked things I was able to go from unbootable to everything back up and running in half an hour.

Rooibos is just an inferior version of honeybush.

Change my mind.

For day-to-day purposes, if you are used to Fahrenheit but not Celsius or vice versa, and all you want to do is get a rough sense of how warm or cold it is outside without having to do arithmetic involving fractions in your head, then remember that there are two temperatures in Celsius that are roughly the same in Fahrenheit but with their digits transposed: 16° C ~ 61° F, and 28° C ~ 82° F. You can then roughly interpolate/extrapolate by about 2° F for every 1° C.
