Kaz, I'm not defending them, but I'm not going marginalize the few things they do well as you seem so willing to do.
Yes, Windows has a lot of bugs. Yes, they shouldn't be there, and if MS was the company it needs to be, they'd fix them and release software without bugs from now on.
But, Office is a suite that is good at it's purpose, you can whine and ***** about this bug or that bug, but that doesn't change the fact that MS products outsell everything else because they are easy to use and get a product out of. You don't have to take a class or classes to learn how to work Word or Excel.
If you want to change it so bad, get a job at MS and make it better, don't just ***** for the sake of it.
