Thanks for raising this thread! I've been wondering about OO for awhile now because it's gotten/got so glitchy that I can no longer use it. I have a Mac laptop, and since the last OS upgrade (to 10.6.8, the last of the Leopards before Lion roared in and vanquished them) Open Office has just become impossible: multiple crashes and lengthy relaunches which offer to recover documents you don't want and never the one you do... etc...) I lost track of the number of increasingly bad-tempered Reports I sent.
Exactly the same situation at school, which has a network of big Mac desktops and is also on 10.6.8. They'd had OO installed on all our accounts (we have to do a lot of things globally) but have now taken it off again, and gone back to Word. As have I on my personal computer at home.
Will watch the new developments with interest. Is LibreOffice available for Mac, I wonder (SnowLeopard)? I admit I haven't done any homework on this yet, so please don't collectively jump on my head if the answer's obvious...
