I wonder how long it'll take before we can have a Mac Pro thread that isn't full of sour grapes about the cost. It's not that poor people can't have it and rich people can. Granted, there will be wealthy people who buy it just because they can. The vast majority of people who buy this are going to be people who spend money on things like:
Auto CAD Mac - $185/month or $1470/yr.
Gemini 5K S35 video camera - $25,000
CryEngine - $1.2 million (ok, so there may not be many of those)
Renderware SDK - $240,000
Adobe Font Folio - $3000
They are going to be people who spend 40+ hours per week on their computers, for whom small speed bumps translate to substantial time savings doing projects for paying customers. Think about it! Many of these computers will see over 6,000 hours of professional work time before becoming obsolete. $2-3 per hour for a high-end professional tool is not prohibitive at all.
I get the feeling that most of us here in the forums are like me. We picked up a used 4,1 or 5,1, modified it as we had the money, love the machine we built, and are lamenting that we can't afford it's descendent. Take courage, my friends! The 7,1 will hit the refurbished market, and eventually the used market, where we can start picking them up, browsing Netkas forums, fighting over whether MVC upgrades are worth it, and coaching each other through foolish self-guided upgrades where we permanently bend the pins.
Patience, my friends...
