Samsung's trying to be a little less square. Its new smart TV remote, debuting at CES, does away with the sharp corners for curved edges, while tweaking the touchpad to combine four-way directional buttons. The end result is 80 percent smaller than last year's model. There are still voice controls that can change channels and launch apps like YouTube, but new are motion controls that let you zip around on-screen menus. Samsung's also added a button to watch two programs at once, side-by-side, which was not there in last year's remote. Some of these things have been replaced by Samsung's higher-end model TVs, which let you change channels and control other functions with hand gestures.
