Any bad bugs show up yet?
I need Office and MS Remote Desktop to work.
Otherwise I use mostly native apps.
I use Office 365 and I haven't had any troubles with it. Only really bad bug I experienced with anything Microsoft is OneNote using my GPU instead of CPU - battery took a large hit on my rMBP mid 2014. Other than that, it's been good.
Office 2011 is fucked, but i'm sure you must use 2016 by now.
Dude.
Just upgrade.
