This is a rather harsh rant, but at least some of it is justified. Remember all the hype last week? Windows 7 RC was good for a year? Well, not so fast and not really. There is a surprise in store starting in March 2010. The surprise that means in effect the "goodness" ends then. Read the whole rant for that and other thoughts.
I don't take as hard a line as the authot, but the author does make some points.
