I got a switch at the time of release, and from what I believe , the earliest models are able to be homebrewed/hacked etc?
I have no interest in that, so was thinking of upgrading to one of the latest models with the new processor in it.
Do the earlier models sell for more than the average $350? Would be great if I can upgrade to a new one with no extra cost.
Even models sold late last year were hackable, so they're not exactly rare.
Someone looking for a hackable Switch might be willing to pay a bit of a premium - but chances are most second hand units up for sale would be hackable. Worst case they can just ask the seller for the serial number.
You can always try putting up a gumtree listing, and include the first 6 digits of your serial number to make it clear that it's hackable.
