Still a new and not-so-user-friendly technology. But if you're fairly tech-savvy and willing to take the time to figure out the bells and whistles, this can be a very useful device if you have many bluetooth enabled products including those not made by motorola. For instance it took some playing around with to figure out how to get it to sync with the palm OS software on my smart phone. It's great for music headphones if you got them. But the catch is you can't listen to music with bluetooth stereo headphone and sync your pda at the same time - the music get very choppy. The software (like some of the other reviewers said) seems it has a lot of bugs with no downloadable drivers from the website. If this is the case I think this should help:[...]It's a 130MB downloadable ".ZIP" file that (I think) is more updated than what the product comes with. BEWARE it's still not compatible for Vista users.
