I realized this is a reoccurring question, and I've read many previous posts including my own on this same topic. However, I'm about to pull the trigger and have a few lingering questions. I own a G5 PowerPC with a beautiful 30" NEC 3090 LCD monitor. I dabble in photography as a part-time business, but this aspect of my life is decreasing due to other demands on my time. I'm selling off most of my photography equipment inventory. Therefore, while I'll dabble in photography, I mainly use my computer for web surfing, MS Office functions, and other non-CPU intensive activities. I don't play games, but I often run many programs simultaneously. My desk space is limited to only one large monitor. I recently downsized homes, so now my home office is upstairs instead of downstairs. When my office was downstairs, I hardly noticed the heat generated by the computer and monitor, but now that my office is upstairs, the generated heat is noticeable and unwanted. I have a PC notebook from work for my portable needs. If I buy a Mac Pro, I'll keep my NEC monitor. If I buy an iMac, I'll sell my NEC monitor. iMac Concerns: 1) Glossy screen. Perhaps this isn't a problem, but as a photographer this irks me. 2) Longevity compared to a Mac Pro (I've had my G5 for about 6 years). Mac Pro Concerns: 1) Heat from the desktop and monitor. Does the iMac produce less heat? 2) Additional cost relative to an iMac and selling my 30" monitor. How much can I sell a less than 2 year-old NEC LCD3090WQXi monitor? I can't find these monitors being sold used anywhere online. 3) Simplicity of form factor with an iMac vs. Mac Pro. Thoughts? Suggestions? I'm leaning towards the iMac, but . . . glossy screen.
