Quick responses as usual. Can always count on R-Help! Bert's point that "it depends" is key, of course. Mark and Karim reminded me that R does not use all cores natively. Putting those together, an expensive quad core machine is not necessary for simple package development, documentation, etc. And for hard core (no pun intended) analysis, a multi-core machine won't be fully utilized without parallel implementation of some type. Thanks all for your advice. Just what I was looking for. Dan
