I've been using the 13" TB i5 model now for the last couple days and here are my current takeaways. First it runs way cooler than the i7 model I had on Saturday so I am happy I made the switch; I didn't need that much power and it saved me quite a bit of money. Anyway, my thoughts:
The Touch Bar is great! I was forcing myself to use it, to get accustomed to it and already it has become something I use all the time--if the app supports it. I can't wait to see all my other apps work with it.
The speakers are flat out amazing! I rarely watched videos on my previous laptops and when I did, I would usually Airplay them to my TV with sound bar, but I find myself watching a lot on this just because they sound so good.
The screen is beautiful, and I like having more screen area than my previous (now my wife's) 12" MacBook.
The keyboard is as good as the 12" MacBook, which I really liked.
Having 4 ports is nice, especially after only having one for the last 18 months with my previous two MacBooks. Also, being able to charge on either side is surprisingly convenient!
Now a bit of negative...
The touchpad is nice, but the sound it makes is slightly annoying to me--a little hollow sounding, not as "tight" as the MacBook--and it does not seem to work as well as the 12" MacBook, especially trying to drag things around with Force Touch activated. I can only rarely make it work. I have, for now, just disabled Force Touch in System Prefs and I can, once again, drag appointments around in calendar and files to my USB sticks.
The battery life just flat out sucks. Maybe 5 hours. Maybe, at best, with medium brightness and me using such power hungry apps as Safari with 3-4 tabs, Twitter, and iMessage. I have a slim hope that Apple will release some kind of firmware or software update to help increase the time, but I am not sure if I am all that hopeful. The battery seems to be just too small for the load it needs to support. But we will see. For now, I have changed a lot of settings to try to eek more battery time out of it. The 12" MacBook made it all day with little issue. I usually only charged it nightly when I plugged in my iPhone and sometimes only ever other night. And, now I am feeling like I absolutely cannot travel during the day without my power supply. Here's hoping for an update...
But overall, the positives definitely outweigh the negatives for me and I will be keeping this. I even formatted my old 12" MacBook and am currently restoring my wife's TM backup to it as I type this. So I am officially a (mostly) happy MacBook Pro user!
