Both sound stupid. That 1 letter would not save the name of it at all. Not forgetting to mention there was a negative stigma attached to the word "vista" in comparison to windows xp and windows 7.
The name is pretty irrelevant considering that the Nintendo Revolution sounded a hell of a lot better than Nintendo Wii yet the Wii still took off.
But wasn't vista just a code name to Windows 7 anyway?
All hail the KING, Andrespetmonkey
