Hi all, I purchased a new 21.5 inch base model iMac in mid June and I am trying to figure out if I should try for an exchange for the refreshed 21.5 base model? I waited 5 months for a refresh but my PC died before the update came. This is my first Mac and i was saving up for a year for this thing and its tough for me to swallow the latest refresh. I would have waited longer if my old PC had not died, but I needed something for work. Any suggestions on what I should do? Thanks!
