1080i is 1920 × 1080 with every other horizontal line being updated
each refresh. Under 1080p _every_ line is updated each hz, so twice
as many pixels must be pushed (but the image won't look twice as
good, as I understand it; I guess it may even be indistinguishable to
many people, even if you have 1080p content).

You can play 1080i/p programming on an 800 x 600 monitor, it just
depends where the scaling is done.
Many HD panels which are 720 pixels high do accept 1080i/p signals
and scale them to fit the screen accordingly. If the panel of my
screen was only 720 pixels high I would be inclined to set my
graphics card to output at 720, however.
You'll pay quite a lot for a name brand TV with more than 720 pixels,
but if you're feeding the image from a Myth box then there's no need
to use the TV's internal scaler. The internal scaler is the expensive
part, and can make a terrific difference if you're connecting an SD
source. I have read some very complementary reports reporting
excellent image quality on cheapo 1080p tellies from lesser brands
fed from a PC at 1920 × 1080; one UK example is the "Goodmans" 1080
panel, a rebranded Tatung, which is cheaper than a 720 Sony or Samsung.
