i agree with all you wrote. unfortunately most of us work in a buisiness that uses only one suite. to say iwork will work in this scenario is not true.
i use iwork at home and it is really nice dont get me wrong. however, it is only nice when i dont have to collaborate with others where these "others" use windows
as far as my analogy, gimp is not like neooffice. neooffice tries to capture every aspect of office. gimp does not try to be exactly like photoshop. however i do see what you are saying
Yeah, they use only one suite of Apps, for the most part, but that one suite is sometimes a rather obscure one. My paper may be switching from Harris to InDesign, which is sort of unheard of in the newspaper industry. The kings in that arena are CSS, Harris, and Quark. And recently, my department stopped using Word and opted for iWork. It wasn't a big surprise to me since they are short for cash when it comes to software but not hardware. We collaborate just fine.
I used GIMP almost 4 years ago and it was cute. I wouldn't have called it a replacement for anything then, now I am sure things have changed. I agree with you, just letting you know that the point I meant to stress was the guidance, which is what a lot of Open Source software lacks, and why I wouldn't use the GIMP --> PS CS3 comparison for the iWork --> Office one.
I would have used a Lightroom --> Aperture for that instead. To be honest I wouldn't tell anyone to not buy Office and get iWork. To each their own, and I have long since left my Fanboyisms in the past, with the guy that thought Apple hardware was the ****. I agree with the other side of the discussion, iWork lacks many features that Office has, but those features aren't important for a majority of users so iWork becomes an option to look at if you own a Mac.
That's really my main point.
