Two things that should probably be discussed before we start making funeral arrangements for the Mac Pro product line:
1. When the Intel transition finally completed with the launch of the 2006 Mac Pro, Apple continued to sell the Power Mac G5 Quad model for those that still relied on PowerPC software for production environments. Last I checked, none of these people are the MacBook Air, iPad, iPhone toting "consumers" and as such, I'm pretty sure that these were solely on sale to appease those in a production environment. So, while I don't doubt that Apple will inevitably stop selling desktop Macs in favor of notebook Macs and iPads, and while I don't doubt that this will happen sooner rather than later, my guess is that the Mac Pro will, somehow, be the last one standing for this exact reason; it offers flexibility found in no other Mac, period.
2. The Article says that Apple is questioning the Mac Pro in ITS CURRENT FORM. Given that we can all agree that the single-processor entry model is overpriced, and that the design is dated (being nearly a decade old), perhaps that means that a revamped next gen Mac Pro might be around the corner instead of a complete axing of the line. Just saying. The wording is vague enough that this is just as much of a possibility.
Let's face it, if you need more than a lower end iMac for any kind of processing power you are either running a poorly coded program or have very flimsy data to encode. Either way it means there are more things to worry about than what a couple of hobbyists think about the end of the Mac Pro.
You mean to tell me that a 12-core Mac Pro with its 12 cores of Xeon, its way larger RAM capacity wouldn't get a Final Cut Pro or Adobe After Effects rendering job done substantially faster than a 21.5" iMac? Because if you are, I think you don't know what you're talking about at all.
If Apple dumps the Mac Pro, then my next update will be a HACKINTOSH.
I will certainly NOT go from my current 2008 Mac Pro to an iMac. If I want to see myself I'll use the mirror in my bathroom. I don't need a glossy screen to do that. Besides, I already have two 24" (non-glossy) monitors, three 1-TB drives in RAID-0, another 750 GB for music, and an SSD and a 2-TB for backups stuffed in the second optical bay. I don't think there's room in an iMac for all that.
I'll just have to immerse myself in the Hackint0sh community and learn what the best dual-chip motherboard is and associated hardware to build a screamin' Hack Pro.
(and I'll turn off auto-updates) and wait until the community finds fixes. I don't mind. Heck, My Mac Pro is still on Snow Leopard (which I prefer). I use Spaces all the time, and last I checked, Lion doesn't have spaces.
My advice, as someone who has Hackintoshed and partaken in many others' Hackintosh projects, is that before committing to your next Mac being a Hackintosh, do a little research now. It's much easier to set up a Hackintosh than it was during the days of Leopard, but build compatibility is highly dependent on what motherboard and graphics card you pick. You don't need to turn off auto-updates, just don't apply the 10.x.x updates until you know what files you'll need to patch before rebooting; it's not hard to stay current with OS builds on a Hackintosh anymore. I'd recommend having a secondary ACTUAL Mac to have around (a) in case the Hackintosh bricks and you need to recover the OS, or in case the Hackintosh suffers an odd problem and you need a computer. If you were considering a 13" MacBook Pro, this wouldn't be a bad excuse for one; plus it's not like the combined costs of a powerful Hackintosh and a 13" MacBook Pro don't still fall short of a single Mac Pro's price tag.
