My biggest complaint about Office for the Mac is that it isn't Office. I've used Office programs since Win95/Office95, and have grown in capability and proficiency with each successive iteration of the suite. Finally went Mac about two years ago, bought Office for OS X 2011, what a major kick in the face. Why, could someone please explain, would it be ANY different than Office on Windows? Who thinks this is a good idea? Isn't the idea to blur the lines between the arbitrary detail of which OS you are using and concentrate instead on giving a consistent, seamless user experience in the software suite itself? Seriously, 75% of the controls, menus, widgets, etc. are named differently, have different icons, have different locations, really?!?😕
And the programs are slow. In Excel, when you right-click a cell in order to bring up the dialog for cell formatting, prepare to wait 2-3 seconds for it to appear. Enjoy the spinning umbrella in the interim. On severely lower powered Windows machines, the dialog appears instantaneously.
For these reasons, among others, I use OpenOffice on my Mac.
