[iBook] Older Powerbook vs new Macbook

[Skygram]

Don,

I cannot for the life of me figure out why your machine would be slower due
to an increase in camera pixilation. There shouldn't be any noticeable
difference. So I am curious what other people will say.

I use an even older iBOOK 600mhz and I have jumped from a 5mega pixel Nikon
D1X to a 12 mega pixel D2X with no noticeable change.

What am I missing here?

Bill
