people use smartphones differently
I use my smartphone for emails, a bit of google map + facebook/twitter etc.
Which rarely go over 250mb a month.
Never used my phone for radio, there is one built in and why use a mobile when I have an ipod touch....
Sorry, it was a little 'tongue in cheek' to be honest.
However the answer to your question is in your second statement. Why not stream the radio instead of using a built-in one as the clarity is a lot better and why carry both a phone and an ipod when the phone can do it all ?
It all 'horses for courses' of course but I got fed up with carrying a phone and an ipod, and having to wait until the ipod was in wireless range to download podcasts, or being out and about with friends and needing to check something on the web which my phone can but ipod cant etc.
Now I have a smartphone which does everything in one package and fits nicely in my pocket and with a decent wedge of data available each month I can use it to its fullest.
Ive wired a USB power supply into the cigaretter lighter and installed a docking station with audio out to my car stereo. The phone will charge, give me directions and play all my music/podcasts through the stereo and when a call comes in it mutes and comes out the speakers.
When Im at work I listen to my music via my laptop using ASIO4ALL putting the sound directly to an external DAC/AMP through to my Senn595's. Thats when Im worried about quality, no matter what you spend on car audio you will always be fighting road noise so Im not that bothered about what quality comes out of the phone. In my experience there is sod all difference between what my ipod touch put out when compared to my Nexus anyway.
If I could be bothered Id set up my server at home to stream my music, videos, photos etc to the phone aswell. Why be limited to the size of your memory card when I can just stream it ?
People have been itching for larger fixed BB caps for as long as I can remember, yet when were given all the data you could possibly want on a phone, we struggle to know what to do with it.
