Sheesh. Now I have to put stripes on my Mini?
Nah, just a chequered roof.
Honest question - in what way would an iMac "not cut it"?
Well, one of the areas I mentioned was music production, and personally I don't find the iMac particularly suited as a digital audio workstation. I have an iMac 24" but I certainly don't use it for that.
One, you want the ability to stick a full sized PCI card into the computer. Two, you want to distance yourself from fan noise (some even stick the computer inside a soundproofed box), which is a no-go with the iMac where the fan is right in your face. Three, you want a huge amount of screen real estate (1920x1200 is nowhere near adequate) because you need a complete overview of a number of audio and midi tracks, the mixer and numerous instrument and FX device panels. I myself have a 3-screen setup with a total of 4960x1600 pixels, and even then there are plenty of windows and panels I have to keep minimized. I guess you could get an iMac 24" and plug another 24" monitor into it, but if you're even remotely concerned about a symmetrical and otherwise aesthetically pleasing setup you're not gonna want that. So the mid-tower form factor is the preferable one.
The thing about music production is that you need a professional setup to get somewhere, but no matter how talented you are you won't be seeing any money in ages, so you're on a budget. It's not just the computer and its peripherals you need, you also need MIDI controllers, monitor speakers, external audio interface and tons of expensive software. So where can you cut costs? Well, one good place to start is to not buy a Mac Pro. Here in Sweden, the Mac Pro starts at 23,995 SEK ($3668), and that's just the bare-bones default configuration -- you'll easily be at 30,000 SEK ($4587) before you check out from the Apple Store. Meanwhile you can get the middle brother of the Dell Precision series (Dell's 'pro' lineup), the T5400, which starts at 10,360 SEK ($1584) and for that you get a quad-core Xeon 2,33 with 2GB RAM and dual NVidia 256 MB video cards, which is more than adequate for the task at hand. Throw in some more RAM and an extra hard drive and you're still only at HALF the STARTING price of the Mac Pro. And that's the upper range Precision series; if you go for the consumer Inspiron series you can get four of them for the price of a Mac Pro.
Then consider that these guys have to replace their machines at least once every 3 years, so it's more than just swallowing
one very tough purchase, you're gonna have to do it again and again.
I work in music software and I can tell you that I've seen first hand quite a few in our user base who have actually switched from Mac to PC over this issue. All the software they need is cross-platform anyway, and for the money saved on not buying a Mac Pro they can afford all that other stuff they need for music production - the dual screens, the monitor speakers, the works. So they ask themselves if they love the Mac so much they're willing to sell their car or move back in with their parents, and if the answer is no, they reluctantly abandon the Mac and take the PC route. And that's not really what Steve and his fans want, is it? People in a notoriously Mac-loving crowd (=musicians) switching to PC?
