I admire his software, but not the computer hardware.
Fair enough. I've admired both over the years, with the hardware probably edging out over software slightly. I've found the hardware to be much better engineered and durable than anything on the PC side.
And how will I get the sound out of an iMac to my stereo without the headphone output? Don't tell me to invest in a Bluetooth add on as Bluetooth compresses the music (again). It was so simple to just hook up a simple wire with a min-plug on one side and RCA on the other. But now simple has gone away.
Over Wi-Fi with either an AppleTV (AirPlay) or an AirPort Express. Both cost just $99. Works great for me. Most of my music is Apple Lossless, and a growing portion of it is downloaded from HDTracks.com in ultra-high fidelity. Sounds phenomenal on my home theater through AppleTV (connected via HDMI).
The prosumer is one that wants to pay consumer prices, or a little bit higher, and be able to do things like add RAM, insert extra drives, upgrade video, etc. the new Mac Pro is way outside of that price range at 2.5 times the base iMac.
The new Mac Pro has been met with howls by those pros who demand open hardware, like the current pro (which looks like my late lamented G5).
I stand corrected, and you're right. Apple hasn't had a Mac that fit that category since the G5 days. And the new Mac Pro (hell, the old Mac Pro for that matter) are definitely out of that price range.
If you're wanting for those days to return though, I think you're wasting your energy. Apple is more about controlling the quality of the UX of their products than ever before. The new Mac Pro is clear evidence of that philosophy regarding their hardware and Apple's direction going forward.
And it makes sense. With the speed and quality of the video processors they're including with most of their models, particularly the high-end ones, and the speed of Thunderbolt 2 and USB 3 ports for users to connect whatever 3rd-party device(s) they desire, Apple sees no justifiable reason to open their hardware up for user modification which could potentially impact the UX in a negative way.
I'm not saying that stance is absolutely right. Clearly you and other prosumers (still) take issue with it. But Apple seems to have decided the prosumer demo, as you've corrected me to recognize, isn't a large enough target market to change their product design philosophy for.
Lament the loss of your G5 if you must, but it may be easier for you to move on by adjusting your workflow to better fit today's technology solutions. Can't stop progress, my friend.
