If I can just put my two pence worth in & call it a tuppence.
I prefer the new system, back then all movies were 2d

No they were not... 3D movies were invented long ago...
2d or not 2d...

I think you're getting confused with theatre.
3d was invented at the same time as red & green glasses.
I believe that 0.99 recurring is not thought to be slightly smaller than 1.00, it is considered to be exactly the same.
There is a thought experiment which can help here.Imagine a stack of discs, each disc having a height of ten times less than the previous one; so you have the first being 0.9 units high, the next 0.09, then 0.009 etc etc. They would form an inverted cone of 0.999 recurring, agreed? Well that cone would appear to all the universe to come to a fine point at a height of exactly 1 unit. You could try to measure how far short of 1 it falls, but all you'd find is a series of ever decreasing discs, going on for ever.
But don't quote me on that, I'm not a mathematician either.

Actually the glasses were invented first. Then they had to create something the glasses could be used for. The age of the truly disappointing cinematic experience was born.

That's quite nice. But the main thing is they're not "considered" to be the same, they actually are the same number. Exactly. Anyone want a proof?
Let x = 0.99 recurring
Then 10x = 9.99 recurring
Or 10x = 9 + 0.99 recurring
So 10x = 9 + x
Subtract x from both sides
9x = 9
Divide by 9
x = 1
So the number x is equal to 1 after all.

.99 recurring is by definition less than one no? And none of your fancy proof will convince me otherwise.

Not sure what you mean there. AFAIR they tried both red/green and polarised spectacles in early 3D films, which was probably back in the 1950s
Ah.. yes see: http://en.wikipedia.org/wiki/3D_film

How much less than one? Zero followed by an infinite series of zeros with a one on the 'end'? But infinity has no end...
