Just to make clear, because a few people have been e-mailing me and telling me to get a Mac:
I don't actually own a Windows Vista machine. I was operating from hearsay. (Which isn't entirely fair, I'll grant.)
I do own three Macs. I record Escape Pod on a Mac Mini, edit it on an iMac, and have a MacBook Pro for getting things done elsewhere.
I used to be a serious Linux geek myself, from about 1995 onwards. I've built boxes on several distributions: Slackware, Red Hat, SuSE, Gentoo, and Linux From Scratch. I've also administered FreeBSD (although not on my box, on someone else's). In all that time I lived mostly on the command line. Which was great, I think that's where the real power is; but also, I never once was able to configure graphics and sound so that they did exactly what I want, when wanted it, without crashing and without lots of extra steps. X and GNOME were things I started up when I needed them and then stopped, because they just weren't stable enough to run all the time.
I don't have a Linux box running any more. This Mac I'm on gives me all of the same capabilities and all of the command line power, but with a desktop that works without my having to dive into configuration files all the time, initiate multi-step sequences to get sound going, or start/stop X to keep it stable. I've also never once had to screw around with drivers or kernel modules to make hardware work. (Although there is a lot of hardware that won't work at all -- but that's true for Linux too.) It's a Unix-like system that allows me to focus on completing my tasks instead of maintaining it.
It's not a perfect machine. I have my share of frustrations with Macs too. And I'm not fooling myself that Apple's a pure and noble company -- they play dirty pool as much as Microsoft does, and sometimes more. Linux is certainly purer from an ideological perspective. But I've had fewer frustrations with my Macs than with any other modern OS -- and I feel like as I grew out of wanting to tinker all the time, of inefficiently diving into the innards of a system just for fun, I also grew out of Linux.
