I've bought a TI eZ430-Chronos 868MHz watch. The watch is MSP430 based, which is a very low-power µC - ideal for embedded battery applications. The hi-lights on the board (that's at least my opinion) are the accelerometer and the RF-Transceiver. The whole kit is shipped including a programming/debugging interface and a RF-Transceiver for the USB port.
I've been working on a remote control application which uses the RF-Transceiver module (USB) to control a music player. It works nearly perfect. The second step was: Make a LUFA- (Lightweight USB for AVRs)-based USB host mode controller for the RF-Transceiver in order to allow stand-alone applications without using a computer. I've already announced this project on TI's Wiki page, so stay tuned.
