When I went shopping for a new kitchen scale, I surprised to see that the high end ones were Bluetooth enabled.  And while I was impressed with the advances in technology, I wasn’t really sure how the Bluetooth function would work.  Does the scale have builtin speakers so that you can listen to music from your smart phone?  Does it interface with your PC so that you can record weights and measures?  Is the Bluetooth feature necessary or only a solution in search of a problem?
