Yeah, I'm going back and forth here. I know what my use-cases are: mostly web browsing, writing, keynote, and email. Battery life is a paramount concern for me more than pure power. I'm still 99% fine in most scenarios with my 2012 MBA, but the keyboard is failing a bit (space bar only works on one side, and some of they keys are a little wonky), the apple logo has burned through and is constantly slightly visible on the other (read: my) side of the screen, keynote sometimes hangs a bit on larger files, and the battery needs replacing.
So I could fix all of that for $500 or so, or I can spend another grand and get a nicer screen, more power, a 3X faster hard drive, and TB3. Or I can spend another $1500 and get a lot more than that, most of which I won't need, but some of which I would use (I dabble in music, and would like to run Acid Pro again.)
So it's a tough call, because realistically the MBA fulfills all of my needs and more - especially the largest and most paramount concern of battery life. But for just a little bit more, I can get some of my wants as well.
It can be a difficult one, I’ve gone back and forth with different MacBook models for a while now, but what I’ve learned is that these “low powered” Macs are still very capable, for example people have been doing photoshop work on the 12 MacBook (I’ll link some videos do you can check them out) while there are even videos of 4K editing, granted the MacBook Pro would be better for those types of things but it can be done. If that’s achievable with the 12” MacBook, surely it can be with the new Air? And possibly more.
I was using a 2011 MacBook Pro before it died, I’ve been looking for its replacement for a while now and I think with this new Air I’ve found it. The screen alone will be a big upgrade, from none Retina to Retina display.
