Is Windows it's different "7" really was derived from Vista? I've head that the development of what has become Windows 7 began during the final stages of Windows XP's development. Initially, Windows 7 was known as Blackcomb (and Vista was known as Longhorn). Blackcomb's origins can be traced back as early as 2000 - Longhorn [Vista] didn't begin development until 2003, and was planned to be an "intermediate" release, to keep the public's interest in Windows alive while Blackcomb was still being worked on. However, many of Blackcomb's features were eventually built into Longhorn (and then other features were again removed), and the result was the [subjective] failure known as Windows Vista. So basically, Windows 7 is 3 years 'older' then Windows Vista, but therefore has had 9, yes 9 years of development in comparison to the 3.5/4 years spent on Vista ?
