I would put all hardware in the same bag - can be good as new after 5+ years - but whatever electronics you want to buy today (be it a phone, "smart" TV, even a car), if you have any experience you know that vendors are now mostly in the business of providing a service, not just a physical product. And that's what you'll want to look up and pay most for. If the stuff becomes incompatible or not secure for everyday use because the vendor stopped (or didn't even intend) to release updates, what's the good?
