Despite Microsoft's excitement at selling four million Windows 8 upgrades in four days, well-known industry blogger Paul Thurott says sales of the OS are "well below" Microsoft's internal projections. Get your salt shakers ready, but Thurott cites ones of his "trusted sources" at Microsoft for the tip, although fails to produce any specific numbers. To be fair though and in hindsight, Thurott does seem to have pretty accurate sources.
Despite the lack of numbers though, investors are a curious bunch, so we're likely to see official Windows 8 sales figures in the not-so-distant future. Until then though, anyone interested in watching the Windows 8 drama unfold will have to wade through a variety of anonymous leaks, specious rumors and fuzzy analyses in order to develop their own judgments.
