Mobile common sense (perhaps)

Once every 18 months ... I change my mobile phone. The tendency is to have a cool mobile phone with camera, music/video player and ... bluetooth. The capabilities of the software included in the new mobile phones are getting bigger maken them close to PDAs being sometimes both in one case.

When using my laptop I normally plug my 3.5 mm audio jack so I can hear everything through my simple, good but inexpensive headphones. Many times, I use the laptop during long (and not so long) flights to hear music or watch a movie, so I push the bluetooth/wifi button of it to switch it off. While in the airport, I checked to see how many bluetooth devices where available within 10 meters ... awesome, more than 20!. Some of them so unprotected that their personal data was accesible.

So, here we have three great ideas that (almost) never crossed the border between Laptops and Mobile phones.

1. 3.5mm standard audio jack
2. Bluetooth on/off button
3. USB data (and power) connection
   

Why do cell phone makers not use the standard jack connection?. Is it because of the greed?. Do they make so much money out of non-standard headphones?.
Now that there are so many phones which are audio capable, they should use this connection to make them more attractive to people wanting to use their audio features.

How come now that mobile phones are bluetooth capable, and that almost everything in the phone can be used/changed through it, the designers do not make this function easily switchable?. On top of that, the energy savings for not havin it permanently off could make them more attractive.

And last but not least, only Motorola has used the mini-usb connector to power the devices and also connect them to the computers. Why don't others follow?

Ok. So, if you are a mobile phone maker and want to win my heart forever, use this three simple ideas. Oh, and please, to drive me crazy add a SD card interface.
