16 MB RAM required, 32 MB RAM recommended... how refreshing! Great work.

For the time when OS 9 was relevant that would have been a RAM hog. My iBook (first generation) had 32 MB RAM on board (plus an upgrade slot, how refreshing).

Sure, that wasn't top of the line, but it would definitely restrict your ability to multi task with other programs at the same time. My memory is that many programs used far less than that, allowing you to easily have 5-7 programs open (I had a RAM upgrade for a total of 64 MB).

Wow. As a comparison, I just opened a new Google Maps tab in Chrome. According to the Chrome Task Manager, the tab alone uses 433mb RAM and 34mb GPU memory footprint after first load.

Florb (an FLTK based map viewer similar to Dillo in specs) would use almost the same RAM as native Mac OS 9 software. And yet people say "JS software it's far better". Even a TCL/TK based viewer with TCCLib/TKLib it's far lighter.

JS is easier to develop, easier to deploy cross-platform, and, more importantly from a business perspective, easier to hire for. So it makes complete sense to use JS in the commercial world.
