I've read most the comments in this article and find a lot of linux people sounding like apple people.
I use openoffice, BUT at the end of the day, openoffice really isn't office 2007 and when trying to be used for more then 'average' office duties, it falls seriously short.
They are more like general tools to use for people with simple job needs.
Also, along the same lines, GIMP is not photoshop nor is OO.o draw/inkscape = to illustrator.
They may work for a percentage of users, but when you get down to it, they are a) lacking in features b) lacking in over a decade of R&D (i'm not including StarOffice years).
Yes, microsoft/adobe's programs are bloated and I'm not going to make excuses for this, but they are serious tools that have been used in work environments for a long time.
In the case of word and photoshop, they've been around longer then linux kernel 1.0.0 has.
Just because you don't like a company, it doesn't make their tools bad.
Using their tools doesn't make you any less a linux user/lover/etc.
