I'm not familiar with the HC1 specifically, but I am familiar with Motorola Solutions products in general. They target enterprise, and typically the devices are ruggedized. They write their own web browser that includes APIs for their built-in peripherals (barcode scanner, MSR, etc.) Their Android devices also feature significant tailoring of the OS, for example they have multi-user support in an Android 2.3 build. In the past year they have acquired RhoMobile and integrated that company's cross-platform development environment and libraries with the Motorola Solutions Android and Windows Mobile devices. They also sell rapid deployment infrastructure and wifi infrastructure, all tightly integrated with their devices.
In short, the pricetag isn't worth it for a consumer, but there's typically enterprise features that draw companies in. Is it worth it? That's another question entirely that I'm not going to get into.
