You have a good point. I should have been more precise; I was talking more about the tippy top of their stack, that is, whatever app framework or tool is this week's answer to some relatively simple question, like how to retrieve results from a DB and display them on a web page, or how to display some relatively advanced interface on that page.

As an outsider (the last time I developed on a Windows platform was 2001) I feel like I see different acronyms all the time in the Windows app-building world, each with a lifetime of about three years.

If I'm in a bookstore, the cover of the latest Windows related magazines always seems to be about some dramatically new way to do some relatively boring thing, and how you should abandon everything you're doing and use this stuff instead.

But perhaps it is not fair to judge the entire MS platform by these more frothy aspects.
