I'm an elementary school teacher who's used Macs for some 30 years. I have a late 2012 MacBook Pro which is showing its age. In looking at Apple's new offerings and trying them at the store they fail in several ways: 1. Cost is way beyond my budget. 2. MagSafe missing is a big deal when you have your computer plugged in with 25+ third graders. 3. The keyboard was just not to my liking and the lack of ports that I need to use without dongles just doesn't make sense. I've looked at MacBook Air, but again, I want a laptop with modern up to date components and I'd like a Retina display. I'm looking for advice and suggestions. I looked at the Microsoft Surface Book and it looked very tempting, but I have no idea how Windows 10 works.
