I think it's pretty significant that IBM is not allowing it to be installed on their company's machines. My own company is taking a "let's wait" attitude, too. So am I, at home. In the past I've accepted all critical updates. Not this time, I'm going to wait and assess the inevitable horror stories, first. To be fair, from what I know about it, I can't see how it would mess with Poser or Photoshop, although if you have concerns about either program, especially on a network you might try contacting Adobe or Curious Labs to see if they have anything to say about it. Symantec has a nice, clear page on how it will affect their products. For the most part, it won't.
