>How does a mac actually make you productive?
I don't have to worry about setting it up, maintenance, having some framework or driver lacking, getting some installation media in case I want to reinstall the OS and in comparison with Windows, getting annoyed by updates.
Besides that, the UI is just great and switching between deskops with touchpad gestures feels a lot more intuitive, as if you had an actual multi-monitor setup. The touchpad is generally great and something you will miss a lot once you got used to it. Unified UI across different programs is pretty nice too.
The integration with their own stuff is great too, synching your notes/music/messages if you have an iPhone over wifi is something very simple but happens with minimal work from you. Generally the biggest pro of MacOS is that you barely notice and think about it.
>Does it never crash?
Had some crashes in Yosemite betas and the likes but yeah, generally it's pretty rare, hence your reaction tends to be not "not again" and more of "woah, this is interesting".
>How is it for office productivity for office 365 applications?
No idea, I am using the Office 2016 pack or whatever the fucking name is, and it's comparable to Windows now.
>What's the learning curve for someone with Ubuntu and Windows Operating systems?
Maybe one day to make it comfortable but about two weeks to really notice how superior it is.
The new keyboard is way nicer than the old one, which was too mushy. The only downside is that it being different triggers people who got used to different ones.
The touchbar is obviously an idea into the right direction but the execution is just like five years behind what it should be. It's great for niggas working with media, and basically irrelevant for everyone else.
As for cooling, you're absolutely right. It's fucked all over the place.
