Hello All - Trying to decide whether or not to sell my iMac for something more portable. I work at a desk all day long at work, so I have found that I rarely use my iMac. I find myself preferring to sit on the couch or at a table with the rest of the family in the room. I do light photography work and some video work, nothing heavy duty. I purchased this machine new about 13 months ago and have only used it a hand full of times, so it's in mint condition. I have an offer on the table for $1,390 and was considering purchasing a laptop as a primary work-horse, which would allow me to be more portable and have the option of working anywhere. Here's the specs of my iMac: 27" display 2.7GHz quad-core Intel Core i5 with 6MB on-chip shared L3 cache 12GB memory 1333MHz DDR3 SDRAM 1 TB Hard Drive, DVD SuperDrive Here's what I'm considering: Either a 13" or 15" rMBP from Apple's Refurb store Refurbished MacBook Pro 2.5GHz Dual-core Intel Core i5 with Retina Display 13" 8GB of 1600MHz DDR3L SDRAM 128GB Flash Storage Intel HD Graphics 4000 Refurbished MacBook Air 2.0GHz dual-core Intel Core i7 13.3" 8GB memory 256GB flash storage Intel HD Graphics 4000 Help me make my decision!!! Thanks.
