It’s really more like a do-over than a sequel. While the original BlackBerry Storm suffered from sluggish performance, glitchy software, and a maddening touchscreen keyboard, the Storm2 fixes nearly everything we criticized about the earlier device. It’s faster (especially when surfing the Web), more stable, and typing is more accurate and feels less like a chore. Plus, RIM has added Wi-Fi connectivity, and doubled the amount of onboard memory. But just because the Storm2 is better than its predecessor doesn’t necessarily mean it’s better than the competition.
