And I am really, really disappointed with what SUN did to that product. I worked at an all MS shop for more years than I'd like to admit. The last 2 years there I used Star Office exclusively and no one noticed. Really, the file formats were that good - everyone else had Office '97 and couldn't tell any difference in my docs, spreadsheets or even presentations (I was careful not to use some of the cooler stuff in Impress that wasn't available in PPT97 - not that I did all that much Office app stuff - I was a VB/Sql goob there).
Then budget cuts came. An assistant vp wanted to do some work at home (Word/PPT/Excel). The CIO said, "You have to buy a license." I suggested he try Star Office from Star Division (personal use license back then was < $40.00). He bought it, used it and loved it. That was 4 years ago. I ran into him recently and he told me that he's been using Star Office ever since. He bought the $75.00 SUN version and said he didn't like the "non-integration". See, I know all the arguments, but from the end-user standpoint, they don't want to have to know that they need app X to create a document of type Y. And the integrated version of Star (v 5.2 and down) didn't require them to know that.
I honestly don't see why a new major was added to what SUN has done with the product. I'm still using 5.2 and imho, it's the best office product available for Linux - and it has the bonus of running on that other company's os (what's that firm's name again? Mega-something, or Something-sloth, or, oh well, not important. :-)
