Why even bother to have windows in a commercial jet?

A Boeing press release makes note of the larger than usual windowns
for their new 7E7 jet. Late model jets are full of video screens at
each seat. Why not use snythetic views of the outside? The view from
a window is limited. With video, all interested passengers could see
outside the aircraft.

Porthole windows on a modern commercial jet don't make sense.

Another different but related topic.

Why do airlines bother to ask me if I want to seat window or aisle?
Why not have the seating pitched for small folks, medium build folks,
and for tall people, this row of seats. (I know, that is what first
class is about.) But it does seem odd to me that the airlines don't
bother to variable pitch some of the seats to accomodate tall
customers.

Now we have the invention of the "knee protector."

A different idea may be for the airlines to just pitch a portion of
the seats to match up with long legs.

Final suggestion. Why don't the airlines allow the stews to wear
sensible shoes? Wearing dress shoes any having to push a heavy drink
cart up the aisle is silly. Plus, stews are really for passenger
safety. The airline should have them dress for that function.
