Exactly, you don't. The Mac Mini is nowhere to be seen. In 3 Apple stores in the NYC area i've visited this past month, each only has ONE Mac Mini on display. A single unit, also hidden on the side, away from the prominent views of iMacs, iPods, and iPhones in the center isles.
I have a sneaky suspicion that a redesign for the Mac Mini is due. It basically hasn't changed since its introduction years ago besides bumps in performance. Though the design is def still very, very relevant in todays computing world (actually i still think its nicer than any Dell, HP, etc...), Apple is know to do a complete 360 and introduce a sleeker product replacing an older product even at the height of its popularity (think iPod Mini). Maybe they can get rid of that huge power brick and incorporate a magsafe-like plug...perhaps a sleek aluminum case with black glass Apple logo... who knows.
The Mac Mini has the potential to sway huge amounts of PC users to the Mac. A slight redesign with a bump in performance would clearly be welcomed.
I don't know what else can be done to improve the Mac Mini, IMHO its a near flawless design, bordering classic status. I honestly love the Mac Mini, but I'm sure SJ and Co can whip something up.
