Same old, same old.
I've been using MS stuff on Macs since Word 3, and I think Microsoft are still the same rip-off company they've always been.
MS people are patting themselves on the back for making the big jump from Office 2011 (released in 2010) to Office 2016 (TBR in 2015).
What they have actually done is played around with the graphics and done a very minor upgrade to a couple of the apps. The sort of upgrade that MIGHT get a .5 indication on anything by another company.
Excel is still 32-bit! Jaw-dropping, just...... jaw-dropping. HELLLOOOOO Microsoft! It's 2015!
Needs to run on Yosemite because your stupid coders can't work out how to make it work properly with older Mac OS's! Would any other company expect to get away with this (apart from Apple of course)?
