Good morning, I am a current PC user with the intent on buying an Imac. The primary purpose of buying an Imac will be for "Prosumer" photo and video editing (lightroom or apeture - Camera Nikon D7000), general web browsing, and Itunes. Like most of you I was hoping for the Imac refresh at the WWDC before making my purchase. However, with all the question as to when it will be, or won't be refreshed/spec bump, I am trying to decide hether or not it's even worth waiting for with the uses described above. Of course I would rather have the most up to date machine but my PC is so out of date, it's not even worth turning on, and it's more frustrating than anything. With that being said; I have been eye balling the 21.5 Imac base model (21.5-inch: 2.5GHz) with the possiblity of purchasing the next one (21.5-inch: 2.7GHz). So here's my question: With what I intend on using the machine for, is it "worth" waiting for, or would I see a huge difference in performance if I were to wait it out the refresh/spec bump? IF we should see one this year!? I know it's a relatively vague question, however any advice will be appreciated. Thank You!
