Yes, it's still meaningful.
If it's hw, you can't update it.
If it's firmware, sometimes you can.
If it's software, usually you can.

(Or if it's an Android OS, and there's a planetary alignment between 
Google, your phone manufacturer, and your phone carrier, simultaneously 
with Mercury being retrograde, the moon being full, and you or at least 
your phone being at a hacker conference or somewhere with 0.5 bars of 2G 
wireless, then sometimes you can upgrade that too.)
