Good luck! I have a feeling you are going to like the 15" model. Far better performance in still a relatively small footprint. I am absolutely loving my 2017 15"; I upgraded from a 2014 15" last month and it is much smaller/ easier to carry.
Either way, though, great machines! Let us know what you decide when you get the 15" in your hands.
Absolutely! I am thinking the same thing.
I will note one thing though: Yesterday, as I said earlier, I spent most of the evening on the 13" watching videos, editing some high res photos in the photos app, browsing websites - nytimes, financial websites, looking at some mail. I also scaled my display for more space which actually made the 13" seem significantly larger in terms of screen real estate (but of course text could get uncomfortable to read over long periods of time.)
Later towards the end of the night, I went back to my 2010 15" and WOW! This thing felt like a desktop! Even right now as I type this, I ca't get over how large the display feels and looks to me! I guess the 13" had successfully managed to immerse me into the smaller form factor and now coming back to 15" feels like a huge difference but its got me suspicious because I didn't "perceive" a serious lack of screen real estate except for moments where windows or the background is completely hidden by an app or browser.
I do find this asymmetric perception difference very interesting: So going from 15" to 13" (didn't perceive much difference staring and working in the smaller screen itself) but going from 13" to 15" felt like a huge difference! What's funny is I'm actually a little discomforted by it? Everything on the screen feels farther apart from everything else, not stretched but on this website/webapage (and using an adblocker), large voids of WHITE blank screen that were smaller in the 13". Wonder if that's an indicator
I still remain a little annoyed with decisions (or lack thereof) because on hand, I realize the 13" is REALLY the machine for me given my use and for portability. Seriously - a beautiful machine in terms of size but yeah, will report back in.
I feel like I'm doing the right thing - getting both machines into my home and testing.
