Hey guys i need some help. Im thinking of getting a 13" macbook air for photo editing because weight is a big factor for me. Im planning on upgrading it with 8gb ram and i7. I'll be using it primarily for editing while im out in the field. I'll be using mostly lightroom 4 and photoshop (i have yet to get photoshop). I also have a windows desktop at home thats running 8gb ram and i5. My questions are:
-is it cost-effective to put in i7 instead of i5?
-will i have any compatibility problems transferring my files from the mba to the windows desktop?
I really dont want an mbp.
