Re: Lack of "Physical" Connectivity
I was thinking of getting the MacBookAir 13", just like your Susan. Now I think the new MacBook would be better for me, as it's lighter and thinner, and I trust that now this is the best Apple laptop for my needs. Because, at the end of the day, it's all about individual needs.
I use my iPad Air 2 for my photos. I find it great and uncomplicated. I used to hate all the process of the SD card years ago. I see no reason why I would go back to technology that is old. I always prefer to try the new stuff.
The new MacBook sounds perfect for mobility, which is what I need the most to work in synch with my iPad and at the same time. Maybe your Susan doesn't need mobility that much, and she prefers to work with her Mac at home. This is why Apple has several options for different needs. :)
