With the touchscreen Storm, Research In Motion offers a response to Apple’s iPhone. Unfortunately, the Storm is more like a flurry, failing to add much more than a trace of innovation. If you use a BlackBerry, you quickly will grasp the basics of how to work this phone. But if you’re a smartphone newbie — the kind of person RIM wants to lure — who’s looking for a touchscreen model, there are better choices. The Storm is sleek and offers nice multimedia functions; videos look great. But navigating the phone can be cumbersome.
