And the ones we get from the research firms will be no better than the numbers they get from Linux vendors and other involved parties. A Google lookup finds over 2000 pages that mention both Gartner and Linux . Most of those, of course, flame Gartner for its cluelessness. Get a clue, PHBs. Because they need objective information from somebody , and they're not getting it from you.
Flames are easy.
Facts are hard. Like them or not, Gartner and IDG traffic in facts, or in the most educated possible guesses. If you have good hard information about how Linux is changing the business world, let them know. Or skip them and let us know. We're in the same business.
