ReadWriteWeb (RWW) published the article “With So Many Alternatives, Why Does Microsoft Office Still Reign?” (based on a Forrester survey). If you replace Microsoft with Esri and Office with ArcGIS, you will also know why ArcGIS still reigns.

Nothing Earth-shattering, and the Forrester survey jives nicely with the totally informal and unscientific Entchev survey of the GIS marketplace.

Excerpt:

“As easy as it may sometimes be to dislike Office, it's hard to deny that it has a pretty robust feature set. For as good as Web-based tools like Google Docs are, they only do a portion of what Office does. And while they accomplish the majority of commonly-needed tasks quite well and benefit from being based in the cloud, this is still not enough for many businesses.”
