In a five-minute video report on the Wall Street Journal, Walt Mossberg discusses four personal technology topics that he believes may prove to be significant trends in the coming year, including a new era of smart TVs, more affordable smartphones and mobile plans, a new wave of more expensive music players and new health and fitness gadgets and accompanying apps. Additionally we should expect to see more tablets and more use of the cloud.

1) New Kinds of TVs: “Yes, I know it’s been talked about for a long time and in fact there are some so-called smart TVs on the market, but I think this year is the year when we’re going to see major efforts emerge on the revolutionizing of the TV,” he says. “Apple in particular has been working on this for some years. There’s been a lot of expectation, a lot of anticipation… I think this is the year when Apple will come out with its effort to radically simplify TV and to integrate Internet video and regular TV.”

2) Cheaper Smartphones & Mobile Plans: “Instead of paying $200 and up in some cases for a smartphone, I think particularly on the Android side there is going to be a significant effort to make phones that can be sold for significantly less so they can be purchased by people with less disposable income, whether in developed countries or especially is the less developed parts of the world.” Walt also suggests a number of small companies will work to offer lower-priced data plans. “We’ll see whether that’s viable, but I think it’s going to be a really interested trend in 2013.”

3) More Expensive Music Players: While most consumers use their tablets, smartphones and devices such as the iPod to access music, “there is a movement among audiophiles to create a new kind of music service and music players that use much higher quality files and really bring in much more of the richness of the music. The downside, these players look like they’re going to cost a lot more.” Walt cites the recently introduced $700 Astell & Kern AK100 from iriver as an example.

4) Health and Fitness Gadgets: “These are things which are either wristbands or watches or other wearable things with sensors that not only… measure your activity and how healthy your day was, how well you’re sleeping, but some of the newer ones are getting into things like reading your heart rate, your resting heart rate, right from sensors on the back of the watch without having to wear a band or some other kind of equipment.”
