My Mac Mini arrived today.
This is a very slick little machine.
I bought the bottom end 1.25 GHz model with the 512MB RAM upgrade. It came to $615.52 after tax. OOBE (out of box experience) was great as it is supposed to be with Apple. All of the shiny surfaces we wrapped in heavier than normal plastic wrap. Physical setup was a breeze. I bought an Apple keyboard ($29) for it as my spare keyboards were all PS/2 and I couldn't track down a PS/2-USB adapter in the local stores. I'm using a Logitech MX310 USB mouse that I already had on hand. My monitor is a 21" NEC XP21 connected thru the supplied DVI-VGA adapter.
Upon connecting the above items and firing it up, I realized just how quiet this thing is. I had my PC desktop machine on a the time. This is a machine that I formerly considered quiet (a P4 2.4Ghz with one of those big Zalman low-noise fans in a Antec Sonata case). I turned it off and all I can hear from the Mini is a slight hard drive whine and occasional chatter as it accesses said hard drive. Any other sound is no more noticeable than the DirecTivo unit I have that runs 24/7 and is sitting about 7 feet away.
The initial boot led me through a series of screens asking for registration info, offering to setup a .mac account (which you can skip and do later if you want), configuring an Internet connection (DHCP from my firewall made this a nobrainer), and time zone. It then put me at the desktop with the updater program listing updates to download (which I'll do in a sec.). Default resolution was 800x600 60Hz, which I promptly changed to a more tolerable 1280x1024 75Hz
I've only just begun to poke around in this little beauty, but so far I am quite impressed.
Next step, install updates and install iLife '05, which came on a separate set of disks (iLife '04 is already installed).
