[...] a
motorized USB "Aquarium" [...]
Whule I can see the point of taking power
from the computer for an
interface converter, keyboard, mouse, something like that, wouldn't
it be simpler if devices like the aquarium, light, etc had their own
mains adapters? Or is a computer now regarded as simpler than a
5V PSU?
Not simpler, but in a lot of cases more portable. You may not use laptops enough to think of them, but
there are a lot of
people who border on attached at the hip to theirs. They may not have
a mains outlet handy, but they *always* have a powered USB port handy.
Oh, I do use laptops. Just not PC compatible ones, and certainly not ones
with a USB port. I'll even admit to using the 5V line on the barcode
reader port of my M100 to power a little hardware hack...
