Just my 2 cent on a Mac. I've owned then for about 15 years. When I left the working world in 2013 with Windows computers I stopped using them. I'll cut to the chase I just retired my refurbished Mac Book Pro that I bought in 2009. I got 11 years of great service from it, but it was getting long in the tooth so to speak.

I recently bought the latest Mac Book air. I bought the i5 with 512 gigs SSD and 16 gigs of ram. Like Bachus recommended get the 16 gigs of ram. IN my case I run Adobe Lightroom on it and it works flawlessly.
