Welcome lori5060. You'll find quite a few helpful and knowledgeable folks here.
I also have a Mac Book Air, bit it is a mid 2013 13", 252 gig SSD model. I am thinking of getting the newest one, a 2017 13" Mac Book Air with a 252 gig SSD. It has more memory (8 gigs) than mine. But have not seen any recent sales yet. Still, Black Friday is next week.
I see you are located in Canada. Depending on where in Canada, we could be neighbors, as I live just south of Seattle. Like Seattle, Vancouver, BC is s gorgeous city, as is (of course) Victoria. I've always said that the area of this part of the world from Portland, Oregon, through Seattle, and up to and including Vancouver, BC is "God's country". That is not from a "religious" perspective, but instead based on how beautiful it is up "here".
Again, welcome aboard!
