Doorbell technology is in growth mode, as evidenced by YourBell, yet another USB-connected doorbell that stores and plays MP3 and WAV files and uses your existing doorbell button. It's similar to that ReBell we showed you yesterday. This one has a 4-inch speaker for so-called "CD-quality sound," and it's made out of your choice of a variety of real wood species. Never mind that its 7.5-inch case looks like it was designed back in 1932—this clunky thing can store 30 different sounds, and a total of around four minutes' worth of audio. And hey, at $89.99 it's $10 cheaper than that strange-looking silver ReBell MP3 doorbell we showed you yesterday. Finally, doorbells are starting to catch up with cellphones. [BCS Ideas]
