Two years ago, even six or eight months ago, I would agree on the killing statement, but now I'm not so sure. It seems they've changed their stance on the Macs. I think part of it has to do with OS X, but the main part is a combination of that and the switch of architectures to x86/Intel.
I spoke with a high-level representative a month or so ago at a trade show about AutoCAD and he seemed to be holding something back. My timescale for the purchase (having to have it) as I told him, was about 2 years out...but I thought about buying now or soon to get acquainted with it. He basically told me (knowing I'm a Mac guy) to wait a year or so before I decide...making me wonder if they aren't going to bring an OS X (MacIntel) version out. I know they've had a lot of interest from customers in a version to run on Linux/Unix (from a security, reliability, and virus-related standpoint I'd assume) so that may be their answer. Makes sense...no need to take into account the various Distros out there (and the compatibility issues that could arise) in the Linux world.
