As a consumer (especially in the internet age), it's in your own best interest to do additional research. I had (still do, but don't really use it now) a Palm T|X and a BT stereo headset. Before buying my N810, I wanted to know if my headset would still work, so I googled around and found this site. It was clear that it wasn't plug-and-play, but I felt up to the task.

I've been around long enough to know that when a retailer says that something is "compatible," there is always a fine print (and Nokia does include some fine print). I've dealt with winmodems and proprietary wifi that required Windows drivers under Linux and printer/scanners that have more features under Windows than under Mac or Linux or special drivers to get all the features of your hardware. That's life.

My advice: save your receipt, be an informed consumer, read the fine print, buyer beware, caveat emptor, and do not taunt happy fun ball.
