First let me say that I know they are two different animals. That said from you experts (and most are smarter than I) would a 2.8 gig iMac with 4 gig of memory, 24 inch screen, optional graphics card satisfy my needs. As I mentioned before I am retired and besides the normal computer uses I do some photo editing with Photoshop CS3 and Lightroom, nothing commercial. Maybe a game or two but again nothing serious. I did my research on monitors, configured a mac pro and then started thinking about the imac. Biggest reason would be desk space. The first question would be the screen how does it compare to the stand alone Apple monitors or say the NEC IPS displays. Yes I know the imac screen is not a mat finish. Is the power supply in the imac large enough to handle USB device power drains? I realize that this thread might be better on the imac forum but I would expect that most of you graduated form the imac. In my switch from many years with using microsoft products I have already purchased and enjoy a macbook pro with the 15 inch screen (small for detailed work with old eyes). As always I appreciate the comments provided.
