I use one for the combination of my "Guest WiFi" and to allow vintage machines to connect that don't support WPA2+.
An OG graphite 802.11b slow one. Natural bottlenecking to make sure guests don't use up all my internet speed. 😁 (Although even 802.11a/g would be slower.) I have it on a HomeKit-compatible "smart outlet" so I can turn it on or off with Siri.
One fun thing about the original graphite models - internally they used a Lucent WaveLAN Silver PCMCIA card. (The same basic card as the Apple AirPort card, but with a big blocky antenna on the end.) My original AirPort Base Station stopped working, so I took it apart, saw this, tried swapping in a Lucent WaveLAN card I wasn't using any more, and voila - it has been working fine for another 20 years.
