I just sold my 2008 MacBook and I'm looking to replace it. I've always had an iMac and the MacBook. The iMac is the 2.16Ghz Duo Core and getting pretty long in the tooth. I had been considering replacing it with a Cinema display and a Mac Mini. Now that I sold the MacBook, I was thinking of an air to replace it. My options in the refurbs are a i5 - 4g ram and 128SD. This would do what my current MacBook does which is just general web surfing and some photo editing when on vacation with it. Then continue with my replacement of the iMac with a mini/cinema display. I'd only be out a couple hundred moving to this MA. OR. Get the i7 - 8g ram 256 SD. Use this for my iMac replacement and add a cinema display. This would set me back $700 for the MA. I wish I could get the i5 with 8g but there are not any in the refurb store. Which way would you go?
