I have been wanting to purchase a Mac mini. Badly. For years. With the March 2009 update, I got very close. However I worry the 2.0GHz will be easily confused (aka more difficult to search for parts, resell, etc) with the older 2.0GHz model. Thus I have been gauging the past, present, and possible future CPUs of Mac mini, in hopes that the next revision is not far. Below is some research. What are your timeline guesses for the next Mac mini revision?
