Year of the Talking Phone And a Cloud That Got Hot

While other industries struggled, consumer technology seemed to march ahead as always in 2011, with important new products and services continuing to roll out. Sure, some tech companies, like BlackBerry maker Research In Motion, suffered reverses. And some products, like Hewlett-Packard's TouchPad, flopped. But many shone. So here is a look at a few of the biggest tech products of the past year, with some analysis of what they signified and what issues they raise for 2012.

• Apple is driving the industry toward simpler, more reliable digital experiences tied into ecosystems of content and cloud services. It is expected to bring out radically new iPhones and iPads in 2012. But can it fend off challenges from popular, rapidly improving rivals using Google's Android operating system? And, in the absence of Steve Jobs, can it keep churning out game-changing hits?
• LTE networks, if they become the norm, could get overwhelmed. To fend off this prospect, the biggest carriers in 2011 began charging more for greater data usage, a move that could curb the spread of innovative services that rely on large data downloads, such as video streaming and sharing of music and high-resolution photos.
• Cloud services are sure to expand in 2012, but questions remain on their reliability, security and privacy. And while most now cost little or nothing, these offerings could become another monthly fee burden for consumers.
• Google may be losing control of Android, as hardware makers and cellular carriers redefine it to suit their own needs, and fail to offer consumers updates in a timely fashion. Except for the Kindle Fire, the operating system hasn't caught on in tablets.
• The big test in television may come in 2012, when Apple is believed to plan to ship a whole new type of Internet-connected TV, which the company hasn't confirmed. A big obstacle: Cable and media companies will have a huge say in this potential revolution, and the current system serves them well.
