At CES 2010, Steve Ballmer revealed that Windows 7 is the fastest selling operating system in history, by far. According to Ballmer “Windows 7 is being well received all around. We saw strong demand for Windows 7 through the holidays – Year-over-Year PC unit sales increased over 50% for each of 4 weeks of Dec according to NPD. This’s on the heels of a strong start to holiday season, where NPD reported that PC sales increased 63% Year-over-Year on Black Friday 2009. Netbooks were one of the hot items where Windows 7 has been strong. According IDC “Mininotebooks: the New PC Phenomena” (which was sponsored by Microsoft), more than 99% of the netbooks sold in US (95% worldwide) now run Windows. And just 2 months after launch, more than half of those netbooks’re running Windows 7.” “As of today, there’re than 800,000 unique apps and 238,000 unique devices that work great with Windows 7. That’s more than a million reasons to choose Windows 7.” According to Ballmer, “Windows 7 will continue to drag PC market along with it. Market analysis outfit Gartner has corrected PC sales forecasts, revealing that it expects a growth of 3% instead of the previously announced drop of 2% for 2009. At the same time, Gartner forecasted a boost of 12% in PC sales in 2010,” revealed Brandon LeBlanc.
