I have the choice between a mac mini and a cube for about the same price. I would have to upgrade the hard drive, cpu and memory right away...but the cube is so cool. Any thoughts?
Agreed. There's just no comparison. Either you're getting a really, really good deal on a Mini, or a really bad deal on a Cube. Either way, get the Mini.
While sexy, the Cube doesn't have much value in the long run. The mini will be able to run the PPC-based OS X software until such time that you can replace the PPC software with a UB of that particular application. My vote is on the mini.
