Well most offline devices don't take minutes now except for the first fix in a long time. It's generally around 30 seconds to a minute.

Usually the almanac is stored in non-volatile memory so additional startup fixes are much faster.

It's more than that too, old receivers couldn't track and download from as many satellites at once. All modern receivers can pull almanac/ephemeris data from pretty much everything they see at once now.
