The Amiga lives!
That’s right, coolest OS from “back in the day” is still alive and still being developed.
Amiga recently published a preview of AmigaOS 4 containing screenshots of the upcomming OS.
At this point it looks largely like most Linuxes, save Intuition’s snazzy menus. Also, there are no descriptions of how a user will interact with the system, but that’s (unfortunately) to be expected from an OS company at this stage of the game.
If you poke around the Amiga website a bit, you’ll find some of the principles guiding the development of the new OS. Quite interesting…
