I am an owner of the "latest" Mac Pro, and I had the liquid cooled PowerMac G5 before that. I don't really know what to feel when it comes to the Mac Pro anymore. I used to compile WebKit a lot, and it takes forever (change one .h file and go get some lunch while you wait). When I got my Mac Pro 2 years ago it compiled it in under a minute I think. It was incredible. The best part was, back then, Xcode had the distributed builds feature, so I could go anywhere in my apartment with my Macbook Air and compiling was still crazy fast since the work was offloaded to the Mac Pro's 12 cores on my home network. Then they removed that feature from Xcode. I also had a two monitor workflow, but then they broke (for me) dual display support with Lion. The Mac Pro also doesn't support the latest and greatest graphics cards, so its not worth it in my opinion to upgrade them for Cinema 4D or games.<p>I don't even know if I mind really. The reality is that for the last 3 or 4 years, it feels like Apple has more and more been pushing me to not really love the computer experience anymore. When I think about my next "big" purchase, I will probably build a PC. I have never done that before in my life. I've exclusviely owned Mac. But "leaving" Mac OS X doesn't seem like a big deal to me anymore. I'll just be trading one set of frustrations (Messages, Notification Center, 5 minute long sleep wake up times, endless WiFi issues, etc) for another. At least I'll actually have fast graphics.<p>And Xcode will suck on my Macbook Air the same way it sucks on my Mac Pro today, so no real loss there, since I don't compile WebKit anymore. Again, its mainly just indifference now. I don't know if I miss the days when this stuff was fun, but Apple has certainly finally succeeded in making me see their computers as just tools.
