Microsoft is ubiquitous. PDFs are ubiquitous. So why the hell don't the two get along?
For those of you keeping score... It's 2011, I'm running the latest and greatest Windows, and I still need to hunt around for some damn third party tool just to print to a PDF file. I don't care if MS Office can write to a PDF. I don't open everything in MS Office. (If I had my way, I wouldn't open anything in MS Office.) It should be integrated with the print system. You have no excuses.
Yes, I know I can print to an XPS file. I can even print to a TIFF using the "Microsoft Office Document Image Writer" (sounds fancy, doesn't it?). But nobody, nobody wants to do either of those things.
