Why is this more interesting for you? I have found living MS free nowadays to be extremely easy. It's not even a conscious effort for me, I simply haven't found an MS product that is the best in its class (or at the very least, best for me). With the exception of the Xbox 360, I do still use that regularly.

It is interesting to those of us who have been using computers for over a decade. There was a time when a great many things required Windows.

I like Microsoft Keyboard 4000. ;) Only thing Microsoft I use at this point, except for maybe Skype now.

Since I work with other people, I still see a lot of Word, Excel and PowerPoint docs and the non-Microsoft viewing options for those remain very weak.

Also, I consider Google's offerings to be a pleasure to use.

ie/windows-plugin-only websites, for one

Which ones? Work related, I assume?

no, mostly government sites that no one has bothered making cross-platform
