Hi Folks, Looking for advice. My wife wants an iMac - she is fed up with Windows and has an iPhone and iPad already. Her demands on the hardware are minimal - normal sorts of e-mail, spreadsheets for her business, surfing, editing her webpage, watching DVDs, etc. No gaming. She needs a DVD player. I am trying to decide between a refurbished May2011 21.5" iMac and a new 21.5". The lack of a built in DVD drive is an issue for the new one - would need to buy an external drive. The refurbished May2011 model would be cheaper and 500 GB HD is more than enough. It looks as if the display on the new model may be better. Thoughts?
