On my last post, I asked people about what open source applications they use. I received 22 responses, and I was a little shocked. Until now, I had always heard people say that they really don't have any applications in Linux that they miss in Windows/OSX. This has changed. Most people said they use the following:
VIM (one respondent saying that software isn't operating system without it)
LateX (two mentions, but that's more than other word processors outside of OOo)
At work, those machines that come in for repair usually have OpenOffice installed. So, I am not all too surprised. I have asked several customers why they chose OpenOffice. Many have responded with the fact that OOo is free (monetarily, most do not understand the concept of open source), and many more responded that they dislike the new ribbon interface of Office 2K7. Mac users tend to use iWork, but many have OOo installed for some less common file formats that iWork does not support.
VLC and Firefox are fairly common as well, although the majority of customers I deal with still use IE (despite having Firefox installed). The main time I see Firefox in use is on Macintosh machines.
So, it seems as if the only applications people miss when using Linux are games and Adobe CS. This will hopefully be less of a problem in the future with Steam coming to Linux. As for the Adobe Suite, I do not see Adobe taking an interest in Linux any time soon, but PlayOnLinux supports some of the Adobe applications. Otherwise, people are forced to look for alternatives to CS. Quite often, people choose Adobe Creative Suite for the layout of the applications, not for their functionality. GimpShop can replace Photoshop, but anything else would require a bit of a learning curve.
