What do you expect to see out of these panoramic windows? The Piccadilly line is hardly the most scenic route in the UK; there's nothing to see but tunnel walls for more than half of the full line. I'm not arguing against panoramic windows if they're easily installed, but that seems to me like it should be a substantially lower priority than air conditioning on the deeper Underground lines.
