I have been running my office from a Rev. A, stock PPC Mini for a couple of years now, with an iBook G4 as my mobile unit. After some debate over whether to go with replacing both units with a single Macbook, I have decided that the 2-computer setup works best for me, so I'm just going to buy a new Mini, which I figure will be good enough for my needs (general office use) and a significant improvement over what I had. And cheaper. And the tiny size is perfect for my tiny office. So now i need to decide which Mini to buy. I can afford to buy the $599 Mini and max out the RAM to 2GB, or I can buy the $799 and probably have to forego the extra RAM. So which is better -- 1.83GHz with 2 GB RAM, or 2.0GHz with 1 MB RAM? Is a 0.17GHz bump more significant than twice the RAM? more importantly, is such a bump going to deliver an extra $200 worth of performance? And even more importantly than that, does a light-usage guy like me even need to worry about it? And hard drive size isn't a big deal to me, because I use external drives for the serious media and archival stuff. Thanks.
