I own the 2.66 i7 version of the 2010 15" MBP (8GB RAM, 128GB SSD+1TB HDD) and am thinking of making the jump to a 13" Air (2.0 i7, 8GB RAM, 256GB). Has anyone made the same switch and have thoughts to share? The benchmarks look about the same, but that never tells the whole story. I use my MBP mainly for photo editing RAW files in Lightroom and occasionally some light video editing. Any big performance differences? Will the lack of a dedicated GPU greatly affect rendering times with video (even if it's just the 512MB GT330M)? As to why an Air and not the rMBP- mostly cost, just can't justify the expense for my use case. Also, thinking of getting a 27" iMac down the road if I need a workhorse. Thanks!
