Transferring files through Bluetooth

ow is it like to transfer files from PC to mobile phone through Bluetooth? I tried transfer a Podcast ("486 BuzzCast 06_01_07 - Flash cache.mp3", 24Mb in size) to my Nokia 5300 through Bluetooth, and it took about 10 minutes.

Conclusion: don't do it. It's a waste of time and waste battery life approach to transfer file. Use a cable instead. After the cable to connect between Nokia and PC is just a generic cable. Nothing fancy, and pretty error prompt.
