Joel Spolsky writes about how Microsoft Lost the API War. It's a long and very insightful article that I enjoyed reading, but now I'm wondering - what's it mean to me?
Personally, I'd just like somebody to rid me of the necessity to use the unpredictable MS Word, but since this will stay in the "rich client" area in the predictable future and nobody seems to be rushing towards HTML as the document format (even though email clients already have pretty good HTML editors), we'll stay stuck with Word as well. Unless, of course, somebody (EU?) forces a standard document format on Microsoft, creating space for interoperable competing products.
