Apparently it means different things to different people, and as such... there's a class action suit against Microsoft. People thought that "capable" meant that the PC would be able to run any version of Vista. Microsoft thinks it means that it can run Vista Home Edition... but not necessarily the other versions.
The funny part was, even the guy at Microsoft didn't know what it was supposed to mean!
Microsoft's director of marketing, Mark Croft, had become confused about the meaning of "Vista capable" when giving evidence.
Croft's explanation was that "'capable' has an interpretation for many that, in the context of this program, a PC would be able to run any version of the Windows operating system."
"Ready," Croft continued, "may (cause) concerns that the PC would run in some improved or better way than 'capable.'"
After a 10-minute break to talk to Microsoft's lawyers, Croft admitted he had made "an error" and retracted his previous statement, saying that by "capable" Microsoft meant "able to run a version of Vista."
