Performance
Equipped with the Microsoft Windows Mobile 6.1 Professional operating system, the Treo Pro offers a user interface familiar to Windows users and integrates easily with Microsoft Office applications. The Qualcomm MSM7201 chipset, powered by a 528 MHz ARM 11 CPU and an Adreno 130 GPU, handled tasks suitably for its era, though by today’s standards, it falls short for more demanding applications. With 128MB of RAM and 100MB of internal storage, multitasking capabilities were limited, albeit expandable through a microSDHC card slot.
