To get Sky+ "free" you actually need two premium channels (and Film4 doesn't count as a premium channel). I am one of the "mad" people paying a tenner a month for access to Sky+.

I can't imagine going back to a non-Sky+ box now, almost everything I watch is recorded. I rarely watch live TV anymore, can't remember the last time I watched an advert
