Hard data is in:
With just a week left in the month, Windows 8's usage uptake has slipped behind Vista's at the same point in its release, data from a Web measurement company showed.
According to Net Applications, Windows 8's online usage share through Dec. 22 was 1.6% of all Windows PCs, an uptick from 1.2% of November. Windows 8 publicly launched on Oct. 26.
At the same two-month mark in Vista's release timetable, that OS accounted for 2.2% of all Windows systems, double the month prior.
Net Applications measures operating system usage by recording the specific operating system and version used by the machines of visitors to approximately 40,000 sites it monitors for clients.
The slowdown in uptake of Windows 8 and its poor performance compared to Vista is a troubling sign for the new operating system [...]
While there are nine days of Windows 8 data for December still to be released by Net Applications -- including Christmas, when a substantial number of Windows 8 PCs may have been given as gifts, and thus not included in the online estimates -- the new OS would have to record an amazing usage jump during December's final week to put it on par with Vista's 2007 pace.
By Computerworld's calculations, Windows 8's share of all Microsoft-powered PCs would have to leap to 4% in December's final week to equal Vista's second-month total. To give an idea of the magnitude of that required fourth-week increase, Net Applications said that Windows 8's share of all Windows PCs for the week ending Dec. 22 was 1.7%, and for the week ending Dec. 15, was 1.6%.
Let's not forget that Vista was released for the general customers in January 30 2007. Well after the black friday and Christmas seasons, and it was also far more expensive than Windows 8.. still did substantially better! But of course, Win8's poor performance has nothing to do with the GUI and usability, that thing is just perfect and all the naysayers are just "trolls".
How much more failings about W8 are needed?
