Windows 8 sales are not doing so well. As a result OEMs and Microsoft are dropping the prices.
"Despite Microsoft's best efforts, it seems that Windows 8 isn't meeting expectations. According to research firm Net Applications, Microsoft's latest OS hasn't even been able to match sales of Vista (which, if you recall, was a major fail for the company). Making matters worse, Microsoft has a long line of unhappy manufacturers — including HP, ASUS, Fujitsu, and Samsung — upset with Windows 8's failure to revitalize an already-sluggish PC market."
