Is the tech world set to split into "those who understand the Sony Rolly" and "those that don't"? No, probably not, but AP's Rachel Metz would certainly fall into the latter category. In her review of the bizarre twitching, wiggling, flashing PMP speaker - which officially went on sale in the US earlier this month - Rachel's few good experiences with the device are pretty much overwhelmed by Rolly's inability to fit into a standard music player niche. Highlights (or should that be lowlights?) include the lack of a headphone socket, the paltry 2GB of storage and the tricky controls.
