Re: here we go again...
Well, lessee. I gave the goddamn ribbon a fair chance and recently re-inserted the menu using this <http://www.addintools.com/office2010/word/index.html>. Suddenly I can work noticeably faster[*] again. I am chuffed. The ribbon sucks. It's was designed to make things easier to find, but if you resize the screen the ribbon shuffles things around and lo, they are gone again. With menus back in I *always know where to find given functionality*. The ribbon is a failure.
Bugs now... that's a common theme through all word & excel since time began. Truth is, they are somewhat better than before, but still excel crashes regularly and word styles cock up if you do anything too useful with them and Access... (shudder). Having seriously less buggy office products would be of real value. But no, facile UI tweaks rock, if you're stupid and in marketing.
I've no doubt LO/OO wil have bugs but it's free.
[*] I could work a sight faster yet if the bloody brokers would quit their endless yapping.
