So I bought, what else could I do?
It turns out that 256M is woefully inadequate for a Macintosh computer. But I knew that already, and have plans to upgrade to 1.25G already underway.
Naming the thing is going to be interesting. I usually use sci fi starship names, avoiding extremely mainstream ones like Enterprise and Galactica... I've had Roanoke (one of the EA destroyers from B5), Serenity, Heart-of-Gold, Bistromath, Morningstar and Synchronicity (two ships I captained in various role-playing games)... I'm thinking of naming it after the ship that is the centerpiece of the sci-fi tabletop game I'm thinking of running.
But that would be a spoiler.
