The M1 Air would have blown people’s minds in 2000. 128MB of RAM was luxurious at the time for a laptop. In 2003 I borrowed and bought several sticks for a presentation (senior thesis on 3D presentation software), and got to 1GB in my desktop and felt like I’d broken some law of physics.
Shortly after I had a TiBook (PowerBook G4) that was _only_ 1-inch thick! Compared to 1.75” Dells my coworkers had, it seemed like the future. DVD drive, modem, Ethernet, full sized DVI port, FireWire, WiFi, Bluetooth, optical audio in and out, gigantic display with a bezel that was unrivaled for years, even among Macs. What a beast!
(I know you meant 2020, but it’s fun to think about the air in 2000).
