I realize that in the grand scheme of things, this is inconsequential. But one of my favorite nicknames of all time was just added to the endangered species list: the TiBook.

That’s right, the sleek, sexy (paint-chipped) Titanium notebook is no more. In Paris Apple announced the new 15″ PowerBook G4 (which must be odd for the French since they are metric) that’s made of aluminum alloy. Aluminum?

Don’t get me wrong here. The new PowerBook is absolutely beautiful. It includes the coveted backlit keyboard, Bluetooth, AirPort Extreme, FireWire 800, USB 2.0, speed bumps, the works. A dream machine it is indeed.

But aluminum? Coke cans are made of aluminum, not the world’s sexiest notebook. And what am I going to call it? The AiBook? Ack!

OK, so I’m having a little metallurgy fun here at Apple’s expense. And honestly, I’m pleased as punch about today’s announcements. We just have to get to work and come up with a new nickname. I’m sure as heck not going to write, 15″ PowerBook G4 every time I refer to the laptop formerly known as the TiBook.

Do you have any suggestions?
