What outdated tech are you still using and are perfectly happy with? - Spinning rust. My daily driver has 7200 RPM drives and an old Core i7-6700 CPU @ 3.40GHz. It's connected to my old Sony receiver from 1998 and using VLC to play music from the 70's at the moment, shaking the house. The drive has registered a lot of errors but keeps on working. - 1990's Sony reference line receiver. It's not green-tech but helps warm the room in the morning, offsetting the wallboard heaters so the wasted energy is a wash. That plus my old JBL's I bought from a coworker in the 90's keep hibernating animals out of the ceiling. - ICE vehicles. Truck, side-by-side, etc... and a 1947 Fordson 2N tractor that still out-performs horses though both tractor and horses have their moments. I buy all vehicles used and extend their life. - Manual hand operated tools. Sometimes battery tools are more of a hassle when I have a quick thing to get done. They are perhaps useful to keep around when electricity is no more. The scythes and related tools are also good exercise. - SFTP for transferring files. It's not really outdated, just fallen out of popular use. To be outdated bots or humans would have to be able to exploit due to being unmaintained or something else would have to be faster. Can't beat lftp+sftp for splitting big files into multiple TCP streams through firewalls. Torrents can come close but have other negative characteristics including being useless for private files. - Cheap wired headphones. No batteries to replace or fail which is good given many Bluetooth headphones do not have user serviceable batteries. No RFI. No hacking or leaking data. Less junk in the landfill. They seem to still be popular for audiophiles. - Wired keyboards and mice. Not sure if that is considered outdated tech. - Wired switches, appliances, lights, Ethernet, surveillance cameras will always be perfectly good for me. - I have a GPS map in the truck but I also keep paper map books in the truck and am happy to use both. GPS may be jammed soon. - All the free notebooks and pens vendors gave me over the years for taking notes, to-do lists, reminders.
