Ooh, got the Mac Mini this morning. The box it comes in is Tiny. tiny! actually. It's very spiffy. More like my DP 1.4GHz PowerMac than my 867MHz PowerBook. And a lot cheaper than either.
I haven't been in a properly quiet environment with it yet, but it seems very quiet so far.
It arrived with iLife '04 installed and iLife '05 on a separate DVD.
iWork didn't get here yet, but should soon. I'm really looking forward to using Pages instead of Adobe InDesign for writing letters...
I ordered a 1GB memory stick from NewEgg which should get here soon. Hopefully someone will post pictures on how to take it apart so I won't have to figure it out. :-)
James Duncan Davidson is also getting a Mac Mini to use as a really fancy DVD (etc) player...
iPod Shuffle? A steal at twice the price (although the comparison should be with other USB drives rather than a memory stick...)
Update: Brad Choate IM'ed me a link to a take-it-apart video. (And roughly at the same minute Lars Thegler added the links to the comments here; don't mind me -- I live under a rock)
