Reading this made me miss BeOS. Blazingly fast UI. Mandatory to use separate threads for app rendering and processing user input to stay responsive under load.

Reading this made me miss BeOS. Blazingly fast UI. Mandatory to use separate threads for app rendering and processing user input to stay responsive under load. File system was implemented as queryable database with arbitrary metadata, so scanning for media was almost instant. Built in components for text rendering, media playback, etc, all had extremely performant implementation. I remember easily playing half a dozen video files simultaneously, butter smooth, with the system still being instantly responsive as if it was doing nothing. On a 200mhz 603e. Those were the good old days.
