9. Microsoft moves to ARM with Windows 8
Microsoft took advantage of the CES spotlight in January to announce that Windows 8 will run on system-on-chip architectures including ARM-based processors, part of its effort to get Windows used on tablets. Other features of the upcoming version of Windows, which will continue to run on Intel chips and PCs as well, include the new Metro interface, which emphasizes touch and a Windows app store. However, the many businesses still migrating to Windows 7 are unlikely to upgrade again soon. And while Windows 8, which could appear on products next year, expands the hardware possibilities for Windows, it's ironic that Apple's iPad already has established such a commanding lead in tablets, a form factor that was long ago championed by Bill Gates. With Microsoft's history of coming from behind in markets to eventually grab a dominant position, though, Windows 8 should not be counted out before it ships.
10. The passing of a legend: Steve Jobs dies
Though it's too soon for history to judge the role Steve Jobs played in shaping technology, the outpouring of tributes around the world when the 56-year-old Apple co-founder died on Oct. 5 was a testament to his iconic status. With Microsoft co-founder Bill Gates (also born in 1955) as a foil, Jobs was one of the two key figures in the PC era, and perhaps the most important business leader ushering tech into the post-PC world. His life was an American success story: The tale of a comeback kid, ousted in tears from his own company in the 1980s, only to revolutionize animated movie-making in the '90s and return to lead Apple's march to dominance at the start of the 21st century. With Apple co-founder Steve Wozniak, Jobs fueled the PC revolution with the Apple II, and after his return to Apple led the company to redefine the music industry with the iPod and iTunes, the phone market with the iPhone, and the personal computer market yet again with the iPad. Jobs' triumphant return was capped in August when Apple overtook, at least for a time, Exxon Mobil as the most valuable company on the planet in terms of market capitalization. Though a difficult and even despotic leader by many accounts, no one denied Jobs' passion and singular position at the crossroads of technology and culture.
