This is not meant to be a "which is best"-style console war question but instead one of personal affinity: which console, if any, do/did you love the most, and why? Whether you're a diehard Dreamcast fan Hello friend!, you have fond memories of your first Gameboy, or you think the PS4 is the best piece of technology of all time, tell me your story and why it means so much to you.
Also, I know we have a lot of primarily/strictly PC gamers here, so if you're wanting to view that as a console, feel free -- whether that's looking at the platform as a whole, an individual piece of hardware (e.g. my laptop from college), a specific time period (e.g. the early 2000s), or some other division. The question is about attachment to a device with a lifecycle and identity, which computers undoubtedly have too, just in different ways from consoles.
