I took a five month motorcycle trip over three years ago, and brought a 13" MacBook Pro (i7, 16GB). I just checked the speed scores and it is slower than the new 2017 MacBook. While my MacBook Pro was very slow stitching files with 100s of megapixels, it got the job done. I often used it at campsites with no power and it never let me down. I returned home with all my images fully edited and backed up. I would have liked something smaller, in both size and weight. That said, if I were to do it again, I'd take an optioned-out MacBook, and let it grind away at those images...So it's slow compared to the larger "pro" models, it can get the job done.
