Performance and OS
Driven by a 32-bit Intel XScale PXA270 312 MHz processor and operating on a Linux-based platform, the ROKR E2 was considered notable for integrating a robust and open-source OS at the time. This allowed tech-savvy users a degree of freedom in customizing their device that was uncommon in many proprietary operating systems. The phone's internal memory was modest at 10MB, with the ability to expand storage via an SD card up to 2GB, catering to users who needed additional space for music and applications.
