Vista, Back To The Drawing Board
You know, it would be quite mean, and actually quite funny, if, now that Microsoft has sent Vista back to the drawing board, to somehow trademark that name for some software package and claim that Microsoft cannot use it. Then, get the case ready. When Microsoft finally wants to release Vista, pounce on them, giving them a dose of their own medicine, forcing Microsoft to have to rename it to something like Smell, Sound, or Taste.
However, as much as we want to do this, unfortunately we know that we want Microsoft to reap what they sow, and that means we must set our own good examples, ourselves. (Darn it, supermike, I thought you were going to mention some GNU/Linux-based software company preparing to do this!)
I'll never forget the court testimony I read in the news a few years back when the judge scolded Microsoft for trademarking "Microsoft Windows". He said to the Microsoft lawyers, "I don't know how you managed to trademark 'Windows'. I certainly would not have permitted it. How the heck do you claim your software is an ordinary object name and get away with it? Can I release a software package, call it Doors, and prevent anyone else from coming out with a software package named [insert your company name here] Doors?" (paraphrasing, of course) He had a good point. Ha ha.
