Hey there,
I own a MacBook Air 2012 with 4 gb. So, do I regret that I have only 4 gb? YES and no!
- Yes, because at the time I bought the machine I was not into photo editing, now, I use Lightroom and my 4 gb are very, very limiting....
- Yes, because I will not upgrade the OS beyond El Capitan, with Mavs,my Air was blazing fast, with El Cap however, things are getting slow
- No,because besides photo editing I don't do anything ram demaning with my machine, so for web browsing and iTunes 4 gb are OK
-> let me tell you that I would never ever get a machine with 4gb of ram. You will Change, maybe in a year from now you will edit Videos, then you're stuck.
My next machine will certainly be a MacBook pro with at least 8 gb and more likely maxed out 16 gb of ram...
