> resource efficiency

Glad that you pointed that out.

Around 2002-2003 I was working an office night-shift, in front of a computer that was in no way the fastest even by those times' standards. But, even so, I was able to follow almost every at-bat in the MLB, live, through their Flash app (while I was doing my regular work in another browser tab). And it wasn't only showing stuff like Batter X hit a 1B, it showed you the exact location and the speed of the incoming pitch, where the ball landed (more or less), what was the out-field formation of the pitching side etc. Really cool stuff given the limited processing resources.

I'd say a HTML+JS solution (which, obviously, wasn't even possible back then for that kind of stuff) would require at least an order of magnitude more resources on the client side.
