6. Voice control

Here's another trend that's got a moderate chance of taking off in 2012: Voice control.

Siri, the voice-control feature in the iPhone 4S, may spread to other devices.

The novelty of Siri on the iPhone 4S -- which allows you to send texts, create reminders, search the Web and much more using just your voice -- may be the start of a new trend in voice controlled devices.

Surely voice control has been around for years? Yes, but it wasn't very accurate.

Siri and its ilk define a new era in which we talk, and our devices understand -- often on the first attempt. Other device makers will likely follow suit. What's more, Apple may use voice control to replace the TV remote .
