I hesitate to put any credence in the Forrester research poll for a couple of reasons: there is no link to the poll set up or test population, the size of the population , and or how they were selected. The way this poll was presented makes my think that it was set up as a marketing tool that could be sold by Forrester Research to the companies listed. I tried to get some info about the survety from their website, but didn't see any.
