I haven't seen that much difference in CS4 where I feel the need to upgrade right now. I have a Nikon D2x, D200, D300. I have a D3 on order. I only use Nikon products. I am a creature of habit. These shots were taken with the D200. To the little guy or girl, keep at it and get good, lots of money to be made..MarkI'm still using CS2. Is there a good incentive to upgrade to 3?
