People have to wait for their vendor or carrier to release an update, or use an alternative ROM like Cyanogenmod. In the case of the latter, Cyanogenmod only started releasing official nightlies for a limited range of devices 2 days ago. Prior to that, it has been a case of scouring forums to obtain unofficial releases of alternative ROMs.
Even after the upgrade has been released, people actually need a chance to perform the update. For some people, that may be several months down the road -- e.g. when they know that they'll have a chance to perform the update and get used to the changes. It isn't a matter of being good enough. It is a matter of giving people an opportunity to perform the upgrade.
