You also have to remember even as late as 2011, Motorola was trying to sell the Xoom tablet as being able to browse “the real internet” because it (belatedly) supported Flash.

But then we still get back to the fact that in 2008, the iPhone 3G had 128MB RAM and couldn’t even fully load a regular web page. When you scrolled to fast, there was a checkerboard while it tried to render the rest of the page. It definitely couldn’t do any complex animation within Safari.
