This is interesting..
I used PC's first, and still do the majority of my job-printwork (well, if you can call projects we've creatively designed around MS Publisher 98's free-object-movement 'printwork') and my internet surfing on my PC and my PC-Laptop. I also usually end up writing papers on the PC, and by seniority I still use my tower for MP3 downloading and CD-burning.
Meanwhile, I've got two Macs - an iMac 800 FP SuperDrive, and a TiBook 866. I initially bought the iMac for Video Editing (which quickly became a new obsession with FCP3) and I bought the TiBook for a power/style/portability boost. I should mention that I also do some graphic design, web design, and other 'creative' type activities. Most of them were on the PC platform at first.
I've slowly begun to migrate my web-imaging-etc work over to the Powerbook (and the iMac) via Photoshop, Pagemaker, and the Studio MX Suite. I like the way Macs work for the 'creative' tasks, and decided to buy my new software on the Mac platform. I'm designing a private studio right now for my basement, and I'm envisioning 3 computers down there. The TiBook will be the centerpiece (All multimedia applications, paired with a Cinema Display and the nifty peripherals to maximize the effect). The iMac will serve as the Multimedia-2 machine (For DVD Burning, and all the things the TiBook can do, when the TiBook is occupied or rendering or whatever.) The third machine, which I will purchase when I put this all together, will be a decent PC. The PC will serve the 'craptime' things (Browsing the net, IM, word, etc.) and will probably be hooked into a Stereo/5.1 receiver for MP3 playback, DVD's and whatnot.
So, as I come into my own (getting ready to start a major new project) and break down just what I need/want, and how to use it, I find the macs strong and reliable for the gruntwork of multimedia. Meanwhile, I want a PC there to pick up the rest of the computing slack... otherwise known as the areas I get annoyed with my Mac. For general use, like when I'm typing on this forum and nothing's too pressing, I prefer using my PC. As someone once said on here a long time ago, "PC's just feel snappier for general use." And that's what I want in general use, the quick-response trigger-finger style.
Of course, when you're crafting a scene in a film or a video, or designing your big website, you don't mind the elegant feel of OSX, and to me it seems to add to the experience. The stability also helps a great deal as well. And we all know you can't use Final Cut on an AMD Athlon.
So I see the point.. were I continuing my current state (Not yet working on said project, and frankly farting around at the beginning of summer break) I'd want the PC, and I would grow frustrated with OSX. However, I think the Macs really shine, when you really get to work.
Purged of numerous Mac-Thoughts,

PS: 10.3 and a 970 that really screamed, might make me rethink some of the above. But I let the guys running this show do the speculating.
