I loved it shipped with 802.11g, then they software upgraded it to 802.11n, added mesh networking, updated the WiFi spec & WPA, added Time Machine backups, and a bunch of other features. I had the Express, so I could use it as a bridge for Ethernet only devices and beam music wirelessly to my stereo optically all 20-ish years ago. I miss how simple and integrated it was and how simple it was to get non-WiFi devices on my network.
