I'm sorry, but I'm going to disagree with you about their products being buggy and ill-designed. Compare Microsoft Office to Open Office. My experience with Microsoft Office is that it is fast, well designed, and I've never experienced a bug while using it. Period. From the little time I've spent using Open Office, it was far slower, and had an inferior user interface. My linux friends even admit that Microsoft Office is far better than Open Office.

Ever tried to write more than a few pages of text/graphics with Word? It falls over pretty soon.

Yes, I do own a copy of Microsoft Office. Excel is okay. Powerpoint so so. Word is terrible. Entourage has good and bad sides - but has lots of problems when there are non-trivial amounts of data.

There is no excuse for the buggyness of MS Word.

IMO they are both pretty terrible.
