For me it all would come down to
cost and
convenience. The channel changing issue kinda means you need to have '
something' in the room with the second TV, even if it's a relay box. And to be brutally honest, I still am astonished that a typical STB costs less than half what a crappy-quality laptop computer costs, so I would not pay $300 for a dual-TV STB if I could buy two "real" ones for $150 each.
And remember, my opinion plus two bucks gets you a cup of coffee.....
