Photoshop CC will be the most intensive use. I shoot big RAW files and do a lot of HDR, my current machine can't keep up. Up to 8 minutes to put together a HDR. Has to be portable as I am going to Australia for a year and will be living out of the car. I will of course be doing the basic internet stuff but I am only concerned about photo editing software. So I am looking at the base 13 MBP or maybe the 256 SSD from the refurb store, both are the 2014 models. The 256 with tax will be just under US $1400, that's the top of what I can spend. I was honestly looking into PC to save some $$, something I thought I would never do again, until I used the new windows on my parents machine. I just can't go back, I need a mac OS. Could I get by on a MBA? I am more hoping I could get with less machine, don't think I'll need more. Oh and I will be able to upgrade in two years so not worried about any future proofing garbage.
