I've got a bit of a conundrum. I have the opportunity to get a very nice price on a MacBook with the Core Duo processor. I've been in the market for a MacBook for a few weeks now, and I'm a bit unsure of something. Is it really worth my extra money right now to go with the Core 2 Duo processor? As my username suggests, I'm not extremely familiar with the Mac world, as I'm a bit of a Mac n00bie. What's the status of 64-bit in the Mac world? It doesn't seem to be faring too well in the PC world, so I wouldn't think twice about purchasing a 32-bit CPU in the PC world. The Mac world brings me some pause though. Should be I be concerned? FWIW, I'm not really concerned about the speed difference between a Core Duo and a Core 2 Duo, as much as I am the 32-bit vs. 64-bit deal. I'd appreciate everyone's input. Thanks!
