Years ago, when I interned at Microsoft, they did a company survey to figure out what to name what would become Vista. The top two names were Windows Hooker and Windows Heroin. True story.
Unlike the other link I saw about this, this one links directly to the article containing the list, rather than the reblog.<p>Really internet - are we re-blogging lists at this point? WTF - some people just aren't trying anymore.
i actually liked "MEGA". the acronym was meh, but "Microsoft Mega" has a nice ring to it. probably would have gotten some flack at release (sega mega drive, etc) but overall i think the best out of those listed.
