I have had both.
In the real world, very little.
In the technical, pixel peeping, non photographic world, the VRII is slightly sharper wide open.
Is it worth the extra wonga?...........depends how deep your pockets are.
but my VRII thermos flask knocks the socks of the pair as that actually holds a damm hot coffee for quite a while & was only £20 
Havent seen a 28-70......but then to be fair I havent looked that hard!
my mk1 is so sharp on my d300 its unreal, on my 700 its not As sharp but still sharp enough even wide open. love this lens.
heres a pic on the d700, wide open no p&p
I don't get why the lens would be sharper on the D300 than the D700, all things being equal it should be sharper on the D700 than the D300, due to pixel sizes on the sensor.
The VRI was optimised for DX format and not FX which the VRII was optimised for.
The VRI was optimised for DX format and not FX which the VRII was optimised for. This is why it vignettes slightly on FX and is sharper on DX.
I believe Canon had the reverse issue with the first version.
I'd love someone to point to a reference for that statement. Its simply not true
The lens came out in 2003 before Nikon had invented FX so why would you think they would optmise a lens for something they haven't built yet?

You may say these are not factual enough but didn't spend a lot of time looking- short of a statement from Nikon many people may always disagree so I'll not get too hung up about it. Having used both on FX and DX I tend to agree that the VRII is sharper on a D3 (and presumably D700,D3s, D3x) than the VRI.

err 35mm film was around for a long time before 2003. I don't think it was just optimized for DX otherwise it would of been labeled 'DX'
Yes it is - checked with my mate Colin Inglis at Nikon UK (well he was until he resigned this week, which was why he wasn't at Focus this year...lol).
Nikon didn't field an FX body when the VR-I was introduced and were telling everyone that they never would (obviously being slightly economical with the truth, but never mind), hence the very slight vignetting effect at some apertures with this lens.
Otherwise the VR-I and VR-II would have exactly the same element groups with only the VR facility being upgraded for the newer model...
Prior to the 70-200 VR-I which was a DSLR-specific lens, you had the AF 80-200 f/2.8 series of lenses, which had no vignetting issues as they were designed for film cameras.
You didn't have DX and FX then- you had digital and film. As a group Nikon created a digital strategy and optmised new lenses against it. I think it's clear they thought they saw the writing on the wall for film and engineered on that basis.
Edit: Missed reply from corba_lite as too busy mulit-tasking while replying- doh!
That's your speculation as to what was in Nikon's marketting departments mind. My simple question nobody seems able to answer is where do Nikon say this is a DX lens? As above I'm not arguing there are a couple of issues with it though.
Nikon don't say it's a DX-'only' lens - it was supposed to be cross-platform - DSLR and film - they made a cock-up.
They tried to cut corners and save some money, thinking hardly anyone used film any more and that no-one would notice the fall-off while using a DX chipped body.
When they realised their mistake (or rather, had it pointed out to them after the introduction of the D3, they made a rather undignified back-pedal and claimed it was 'optimised' (not specific-to, you notice) for DX.
And then quickly introduced the VR-II...

I agree with most of that - but the VR-II was on the normal upgrade time line
Bloody hell, I thought it was a simple question!!!! LOL! Interesting read mind!
Yep a simple question that gets an in-depth answer
