Yes. That's the great thing about the a cross-platform toolkit. Keep in mind though that explicit control of device-specific hardware (bar code scanner, etc) will not be there for non-Motorola devices however, native extensions can be built to do so.
For additional details on supported devices and platforms, see the documentation here Rhomobile | Supported Platforms, as well as this link Cross-platform Application Development Made Easy - Motorola Solutions USA
Thank you for your answer, actually I managed to install it but when I run it shows me the following message: "RhoElements is not a valid Windows CE application".
Do you know a good tutorial on the subject?
