Quote - I'm looking at picking up a new mac - macbook laptop...
so what would be a better 3d machine -
a laptop running 2.0 ghz core two duo and 4 gig ram or...
a laptop running 2.4 Ghz core two duo and 2 gig ram.
What is more desirable, a little more processor, or double the ram?

I've been using the same 1.25 Ghz emac with 1 gig ram for the last .... six years.  i ready for a new computer.

The desktop is killing me.  I'm fairly athletic, but sitting down using a Kinsington roller mouse is killing my right shoulder.  I can run 5 miles in the rain and feel better the next day than if  I run this mouse for ten minutes.  The ergonomics of this desk must be all wrong. 

I'm hoping the laptop will allow for a better setup... maybe a wireless keyboard and pen tablet...
any suggestions? 

For a MacIntel, no doubt : processor.
You will easilly (and simply) upgrade memory later if needed.
Good choice anyway - HF
