Red-Letter Day or Red Pill?

Today I received my new MacBookPro. It's the first Apple computer that I've owned since the ][e that my folks got for me "back in the day." It also means that I've added to my OS collection yet again; my current tally includes not only OS X and Windows, but also Solaris, OpenBSD, and Linux... I've only been using the system for a couple of hours, but I'm digging it so far... Of course, it's hard to argue with the horsepower that this baby has! I think my poor little Athlon XP (Barton) desktop is going to start feeling a bit lonely...
