My daughter (15) has recently gotten into photography pretty seriously. She worked all summer to purchase a used DSLR and really enjoys composing her shots specifically how she wants them to look. I'm impressed as she hasn't ever really been interested in anything. So now she has quite a few pictures that she's satisfied with and wants to start experimenting to see how other well known photographers or those she follows on flickr create their signature looks. I have always enjoyed editing photos much more on Mac than on PC, despite using PC at work daily and home occasionally. But, I don't want her spending her hours of free time on my iMac. TO THE QUESTION....Is a C2D Mac Mini with 4 or 8GB of RAM, 240GB SSD and Firewire 800 External, and 20" monitor going to be adequate for doing her thing in Lightroom and similar programs? . The other possibility is a 2009/2010 white poly Macbook. I have everything but the Mini/MB and the ram. So we're talking about $200 tops for the Mini and $250 for the MB Thoughts?
