Electronic devices keep state in all sorts of strange ways nowadays. If you have the money, the safest strategy is to shred everything rather than having to do a ton of research figuring out whether a given device needs it.

For example, lots of people don't realise how many printers are vulnerable to recovering previously printed documents. In the past, you might have just opened it up and ripped out the hard disk and memory, but nowadays with NAND and DRAM being soldered onto motherboards, do you really trust that's enough?

Why merely shred, when you can truck it down to your local steel mill and melt it in a blast furnace? Ain't nothing coming back from that.

Do I detect a reference to Terminator 2?

Some of that was recovered in T3. :D
