So always update it whenever there is a firmware update available right?
As already mentioned, yes.
This is not specific to firmwares. Updating is
always the preferred way.
It is a trade-off between features/security and compatibility/usability.
The general consensus is to always update, since it has more pros than cons.
Otherwise there is a risk like if the firmware is too old?

So basically if someone didn't plug their nano ledger s into their computer in over say 6 months, there is a risk of not being able to update the firmware?
I have already replied to this:
[...]
However, in the future this should NOT happen again, since ledger live is doing incremental upgrades if a full upgrade isn't possible.
This means, if you can't update directly to the newest version, it will first upgrade to the highest possible version and afterwards to the next highest possible version.. etc.. until you reached the latest available version etc..

To me, that sucks because if someone wants to store their coins on a wallet like this and keep it untouched... and then they can not update the firmware, that seem to be a huge issue... don't most agree?
Not necessarily, you can still update the firmware without 'touching' your coins.
Simply plug in the nano s and update.
I mean if someone doesn't touch their ledger in a long time... i mean not being to access in their coins because of firmware... that is kind of ridiculous.
Your can always access your coins in any other BIP39 compatible wallet, as long as you have your mnemonic code backed up (which you always should!).
