If you do any work in the manufacturing arena, as we do, you might be shocked to find that one of the OS's still running, and running well out there is DOS. Yes, DOS. Many of today's machine tools benefit from the lightweight old dependable operating system that appeared decades ago when my hair was a lot less grey.
As well, Microsoft is earning no friends with a recent rumor/announcement that Windows 8 is coming out. On my last business trip I visited with a large international company whose VP of Information Technology was truly well, pissed off, that Microsoft bungled Vista badly, finally got what seems to be a good OS back on the market (Win 7), and then (!!!) announces another version coming.
It seems the number of people sick and tired of Microsoft is growing. Office 2007 was largely a bust and finally, as companies start the move to Win 7 / Office 2010 its becoming more and more apparent to people that Microsoft is less interested in "improved technology" and much more concerned with creating revenue streams.
As ever, SQL Server seems to stand alone and apart from these shenanigans, but that viewpoint is also 'melting'. For guys who spend most of their time with SQL maybe driving huge databases for web sites or vast businesses, sure SQL 2008 R2 is an "improvement" - but there are thousands (maybe more) of other companies who just want a good database and for them, SQL 2008 comes off as just another upgrade to fill Microsoft's coffers with little to offer them.
This is the price we pay for a lack of good competition in the business OS and Tools arena, but as ever, whatever OS and software gets the job done is often what people stay with - especially in this time of tightening corporate outlays for huge upgrade projects that in the end, upgrade users to basically the same thing they already had.
There's no such thing as dumb questions, only poorly thought-out answers...
