To other people reading this thread, please post your message indicating your interest in this keyboard.
Remember: You can reuse this keyboard on multiple Bluetooth compatible devices, including an iPaq, a Symbian phone, or even a plain laptop/desktop Bluetooth dongle to use as a cordless keyboard to use from a sofa too (for living room media computers, jukebox remote control, etc). The addition of 7290 support would no doubt cause extra further interest in this tiny keyboard.

Keyboard Review #2
This keyboard fully implements the Bluetooth HID profile (generic keyboard protocol); so all RIM would need need is to write a standardized Bluetooth HID keyboard driver. Since this is a plain vanilla protocol, it is worth investigating if this is something simple that can be done in one night by a single computer programmer to make it work wth the 7290!
