The word "rants" in the URL pretty much eliminates it from consideration as a serious site.

To me this seems high. There is still a lot of Solaris, AIX, and HP/UX out there not to mention Windows: Especially on Exchange and other nondatabase  servers.

My experience in the US, which to be honest includes almost no company that would be defined as "small" is that the smallest ERP vendor they deal with wouldn't even consider saying MSDE to them for fear of being laughed out of the building.

I was consulting with one major vendor about 5 years ago and they called me because when they hit the Asian market with their product running on SQL Server and Windows they couldn't even get an appointment to demo it.

Obviously your experience in your country and other people in their country may experience different things. But here, in the US Pacific Northwest, anyone that offered a serious product on MSDE would have a hard time getting past the receptionist even if they brought her flowers and a latte'.
