	Well, whatever.

	Betamax gave you roughly ~400 lines, that's about 65% of Pal/Secam
	resolution (before that Secam was 825, that's before they switched to color)
	and about %75 of NTSC (Never Twice the Same Color :-).

	Don't know if there were any variants of NTSC Betamax, as with VHS
	(NTSC 3.58 & 4.43).

	VHS gives you roughly ~250 lines, with probably better color restitution,
	which might explain the consumers saying they liked the picture better.

	Doesn't say anything about sharpness.  It's a bit like the CD vs. vinyl
	argument: some people say vinyls and tube amps sound better.  It's
	a question of taste, and the fact that CDs sound too "clear" for some
	people, especially when they've been used to the post-master audio-spectrum
	compression of vinyls.
