According to this Wall Street Journal article:
"Some Storm owners have complained about everything from clunky software for typing on the touch screen to the device's sluggish performance with basic tasks like dialing-by-voice or taking photographs.
"I found myself wanting to throw it in the ocean due to my frustration with its overall usability," said Steven Golub, a longtime Verizon customer from Morristown, N.J., who bought the Storm the day it was released, but returned it a few weeks later."
Other sites like CNET crave and Apple Insider are covering this too.
