Nikon D70 - Do pictures require Photoshop fixing?

Dear all,

I am about to take the leap to digital and have been looking at the
current range of post =A31000/$1000 DLSRs and am opting for the D70.
However I have read in magasines that the pictures taken by the D70
very often need to have levels/contrast fixed in Photoshop. Is this
your experience?

I am likely to edit my best shots in PS anyway, but if I am away on
vacation, I want to be able to shoot 200 pictures in JPG and get them
printed with minimum of fuss - am I looking at the wrong camera?

Last point, if the answer is "yes you have to fix all your pictures",
can I just set up a "Auto Levels/Auto Colors" action in PS, and
automate the lot? This would be an acceptable solution for me.
Your thoughts are appreciated.
