Hello hello. So, I have sold my Powerbook G4. Originally, to get a MacBook. However I am not impressed with them. So I am looking at the iMac. Before I went to look at the MB, I decided that it would be between the 17" iMac and the MB. So when I went to Apple Store that is about 50 miles from me. I only looked at the 17" iMac. So I have been browsing around and looking for ideas, then I noticed the massive discount on the 20" iMac Core Duo. It is in my price range for sure. So, I can't really visualize the difference between the two since I didn't really look at the 20" iMac in the store. I do photography, I run aperture, I also do web design and other random things. I definitely think the real estate on the 20" would be nice. However, if I buy the 20" I will have to wait to max out the RAM because I won't have the cash to do so. To make a long post short, is the difference between a 17" and a 20" iMac highy noticeable? Will the 20" promote better workflow? Thanks a lot!
