Mobile-solutions provider Symbol Technologies announced the MC50 family of handheld PCs, which it dubbed “enterprise digital assistants” because of their barcode-scanning and VoIP features. Designed for enterprise workforces, the MC50 is available either with or without a thumb-able QWERTY keyboard. Both models run the Windows Mobile 2003 Second Edition operating system and include 520MHz Intel XScale processors, 128MB of memory (64MB RAM and 64MB ROM), 240 by 320-pixel TFT screens, an SDIO expansion slot, and built-in Wi-Fi radios.
