Hello, I am 14 and have been saving for a while now and wish to get a MacBook Air because of the portability (I will be using it at school as well sometimes). I would like to use it for some light to maybe medium video editing and some light photo editing in something like photoshop or Lightroom. What would you guys recommend are the appropriate specs? I would prefer the 128gb storage because it is the cheapest and price is an issue for me.. I currently have an Acer with 4gbs RAM and 2.16GHz Intel celeriac processor and 500gb HDD. It is the slowest and worst machine... Would even the stock 2013 - 2014 MacBook Air be better? I wouldn't mind getting a refurbished model because it is a lot cheaper. Thanks.
