One of the standard axioms of writing/publishing is: "write about what you know." Well, Glenn DOESN'T know from experience, so he's cribbing from other sources in order to present his "article." I'm not quite sure to whom the article is actually targeted, but I can pretty well guarantee that as an adult, I would not make any critical buying decisions based on this. There is (in my mind, at least) a huge credibility issue. If I am looking for information on specific equipment in order to make an eventual decision as to where/how I"ll spend my money, I am going to go to the experts, and there are plenty to be found on the internet. Heck, many of them are right here! For instance, if I were considering the 30" ACD, I'd pay attention to what has been said about it from those who have actually USED one, who OWN one.... Before I plunk down the $$$$ for a Mac Pro, I'm reading the comments of those who already have begun using one, I'm reading the discussions about which graphics card is the best choice for the use to which I intend to put it, the discussions about the amount of RAM which is optimal, etc......
OK, this is going to sound snotty, but I am much more likely to consider advice/recommendations about which Mac to use for photography from adults who actually OWN and/or have at least USED the computer and photography equipment discussed rather than a 14-year-old kid who still is shooting with a P&S and who is still wondering about which DSLR to buy.
