I know there are a million threads like these but I could use some advice... I am looking to get a new machine I think. I currently have a 2011 MacBook Air 13" with 4GB Ram and 128GB SSD with the 1.7. It's fine but not super powerful by any means. I also have a 27" iMac that is basically brand new with the 3.1 i5 and 12GB Ram and 1TB HD. Here is my dilemma. I just moved back home for the time being to save some money up for a house and to invest in a business I am starting and I basically only sleep there. Being at my parents house isn't very fun so I try to stay away 99% of the time. This makes my desktop almost worthless. I haven't even been on it in weeks. The things I use my computer for are Photoshop, Ruby on Rails Development and some very light video editing / importing and schoolwork (I'm also in college finishing up with about 1.5 years left) I am considering selling both my machines to either get the retina MBP (for lightness and power) or the legacy MBP (for power and stability) or maybe even a fully decked out MBA (for price) The thing that really is hard for me, is if I sold the 27" iMac AND the Air, I would probably just get enough to get retina alone or legacy. Even though the iMac was worth $2100 brand new, I bet I could only get 1700-1800 for it and after eBay fees or whatever, then even less. And the Air maybe 700-800. So that would be like 2400-2600 which would be the cost of the Retina or Legacy with decked out. Traded 2 good machines for one sucks, but I just don't think the Air I'm using will cut it for all that work, plus I could use more screen real estate. The new air, I would get 8gb ram and the best processor, but the downfalls are the screen real estate and lack of video card for things like video editing and importing. But after getting $2400-$2600, It would only cost 1600-1800$ for the new air. Any thoughts, suggestions, ideas would be great!
