UPDATE: There are now 14 articles on the Mac mini. Useful bits: the Mac mini can be used on its side (though I don't think it has rubber feet for that like the old Mac IIci used to); memory "should" (but not must) be installed by an authorized Apple tech; the included video adapter doesn't have a short cable like the ones for PowerBooks, but is functionally the same; VGA video has a maximum resolution of 1920 x 1080 pixels, slightly lower than the maximum DVI resolution of 1900x1200; and Apple didn't add a lamp to light up the logo on top.
Macworld also has some more spec info on the Mac mini that isn't apparent from Apple's site yet. (Key point: the drives are only 4200 rpm.) Finally, a German site has case and motherboard closeups. Check out the density of of the components in the top middle of that first shot—click to zoom in.
All sorts of cool tidbits here:
The Mac mini info is likely to appear soon. No updates yet for iLife or iWork. Have fun.
