Mac mini Includes AirPort, Bluetooth
The higher pricetag on the new Mac mini with Intel Core Solo or Duo chips obscures the fact that it's not just faster, but includes both wireless networking options previously sold separately. The $100 or so you'd pay for AirPort and Bluetooth 2.0 with a $499 first-generation Mac mini is built into this unit, probably due to very high demand for that built-to-order option.
The new Mac mini base model includes more memory, too, and gigabit Ethernet, but its more powerful video card uses main system memory instead of dedicated video memory, obviating that price difference.
