I am looking into getting a MacPro. I have no illusions about my needs: I do not need a MacPro. I am buying it for several reasons: 1. I enjoy the design, and design is very important to me. I have a restored G4 cube sitting on my desk and I feel the nMP is the new Cube. I fully admit this is the primary reason 2. I want to not own a laptop, in an attempt to not be on the internet all the time, everywhere in my home. More "work/internet is for the desk, everything else is for real life". Plus i have my phone for that. 3. I would like it to serve as a digital hub/server; stream movies etc to my Apple TV (currently I dont have anything resembling a server but I would like to get plex set up or at least all my movies on DVD that I ripped years ago). 4. Although expensive, they seem to last a long time; my friend owns the tower and it has lasted for over 8 years with excellent performance and rare upgrades. I expect the nMP to do the same. But the nMP is not the tower. 5. I use Lightroom, but obviously I dont need a MP for that. However, my laptops tend to choke on large photofiles especially a few years out. 6. I dont want an iMac; I have had one before and I don't like them (for various reasons). Mac mini is out for performance reasons. And I only want to manage one computer. So my options are to either continue with laptops or to get a nMP. Will the nMP last me for 8-10 years? Is the model I am looking at appropriate for lightroom? Are the GPUs/processors upgradeable? I know the MPs are due for a refresh but I am looking now anyhow...purchase wouldn't be made for at least 6 months. Im looking at quad core with 16gb ram and the D300s. My other option is to get a laptop and leave it permanently plugged in and on. The difference between the two is about $1K, which to me is worth it IF I can get adequate performance for twice as long as a laptop. Although I have been reading about the nMP, most of the benchmarks seem to be about 3D rendering performance.
