I remember needing to regularly upgrade a single computer system for thousands of strikingly more valuable dollars. Thankfully, my expenditures have fallen during the last four decades. I simply have more devices.
We have the large all-in-one I'm typing on right now. We have a traveling Windows laptop for vacations. We each have an Android phone plus one Android tablet. Also, there's an Nvidia streaming box and a half dozen Google Home speakers and hubs scattered around the apartment. 
So surely, I don't require another computer. However, rather than spending thousands, I ordered a tiny Windows 11 PC that should arrive by Amazon tomorrow. I could use it as a media server and connect the networked movie drive to it. Or I could keep it updated as a backup home PC. Maybe I'll pop it in a backpack when we travel. Any flatscreen TV could attach to one if its two HDMI ports.
Whatever its ultimate use, I couldn't resist the urge to play with a new device boasting a one-TB SSD, 16 GB of RAM, and an Intel Alder Lake-N95 for a total of just a few hundred of today's much-less-valuable dollars.
