I just did a little googling and it looks like the MBA isn't really anymore powerful than the i5 in the 2017 MacBook 12". Is this right? I love my MacBook. I'm just a casual user that likes to read the news and do basic office level productivity so it works great. My girlfriend is finishing med school and her Mac is probably 10yrs old with too small a HD so I was thinking of surprising her with a new one. Figured I'd take a look at the MBA. Thoughts? Also is the screen pretty good? I watched a review saying the Pro had a brighter screen.
