Apple goes Intel.
It should be interesting.
I don't have all that much invested in what kind of processor is inside of a computer, x86 or PPC. I've owned and used Macs since System 7.5 -- but I've had my share of experience of Windows 3.1, 95, 98, and XP at work -- and OS X has been one of the most interesting and satisfying experiences I've had on a computer. That is probably what will continue to drive my computer-buying decisions in the future. When it came time to buy a new computer four years ago, I considered switching to a PC, but stuck with Apple and bought an iMac, and I haven't regretted it a bit. Once I loaded OS X 10.1 on it a year later, it would have taken a huge change to make me look at anything else. When I wanted to buy a laptop, the only choice was between an iBook and a PowerBook.
So while I'm curious to see how this is rolled out over the next two years, I'm not quite ready to panic yet. After all, my beef was really never with Intel, but with Windows. I heard arguments why the Power PC chip architecture was superior to Intel's x86 design, and I nodded along, but I admit that I understood only the most superficial elements of it. There may be reasons why this is a very bad thing, but I'm not the one to argue that case. In fact, right now I have more questions than anything, and eagerly await the shitstorm that is sure to ensure over the next 24 months until the transition is complete.
