I tend to find it quite interesting to see how quickly a new operating system or browser is picked up by users.

I remember Vista being a slow take up – so I thought I’d see if I was right about that whilst also checking the progress of Windows 7 in the market.

I’ll be using two of my sites (both over 500 unique visits a day in non-tech areas) for the ‘tests’.

Launch Dates:

Windows Vista was launched on the 30th January 2007.

Windows 7 was launched on the 22nd October 2009.

Windows Vista usage for week 4 months after launch. (7th February 2007)

Windows 7 usage for week 4 months after launch (22nd January 2009)
