It's not as though 2 MB is a particularly low cap when you consider that all Amiga graphics cards, intended to use much bigger screens, are capped at 4 MB. A contemporary PC graphics card had something between 768 kB and 2 MB. Given the total addressable space of a 68000 or 68EC020 (8 MB fast), it was also well-rounded.

The access from CPU to graphics memory is much faster on today's PC than it was on the MSX or Sega, where access to graphics memory was so slow that you couldn't dream of drawing bitmapped graphics. The Amiga approach is more general, as much of the Amiga's hardware is, at the cost of being uncompetitive with "idiot savant" technology.
