Update* Used/Refurb I'm really looking to upgrade to a new, lighter, and faster machine, and I believe the Macbook Air best suits the bill. The 5 year old (pre-unibody) MBP is too heavy to constantly transport (I lug it around every day) and is slow compared to the newer models. I've noticed the older i7 256gb's go for around 1200. This is a steal compared to what this computer cost. I've figured by selling some camera equipment, this would factor to about 300 overhead on my end. In terms of usage, the only intensive tasks would be Lightroom, Photoshop CS6, and iMovie. I assume none of these would tax it too hard. Is it really worth paying the extra 300 (2012 model is 1500) for 8GB ram? I assume these computers are going to hold their value relatively well, so I could always offload it in a couple years if I wanted a redesigned model. Thanks for the help!
