There were three new iPads (the iPad 3 in March, the iPad 4 in October, and the iPad Mini). iOS 6 dumped Google Maps in favor of Apple Maps, which was a huge failure. Samsung took off with the Galaxy SIII and Note I/II. 3D went over like a lead balloon in televisions. So much so that TV manufacturers stopped including glasses with purchases. Facebook broke a billion regular users, and celebrated by buying Instagram while their IPO tanked on the first day.
Microsoft changed their focus to a devices and services company, leaving operating systems and software to the shadows. They launched tablets running Windows 8, and they aren't selling well. Windows 8 isn't a huge success either. However, this is definitely the year that the touch interface hits mainstream.
