After reading this AnandTech review of the Mac mini, I am thankfully no longer interested in one. The graphics framebuffer is too small for it to function smoothly at 1600x1200, the native resolution of my Samsung LCD. So that takes care of that.
My Samsung doesn't do 1600x1200. I might still go for the Mini, although I am disappointed about the lack of a REAL hard drive. I'm going to wait and see what kinds of made-to-order options there will be in a while, after OS 10.4 comes out. If I can get a RAM upgrade and a 7200 rpm hard disk, I might go for it.
