I think I keep my current album on my phone, and whatever pics and videos I have taken that day, or sometimes that weekend. That's it. The only reason I have our album on it is to let people hear it and to bluetooth it to them in pubs as and when required. But there is no phone with decent audio playback so I wouldn't use it to listen to tunes unless I had to.

Similar with photos - I don't want local storage of photos on my phone. They serve no purpose on a small device. If I take a picture with my phone it is because I will be facebooking/tweeting it soon after.

But I never go more than 2 days without plugging the phone in to charge, and that automagically hoovers all the media files off into my terabyte storage disk.

My very non-techie wife forgets to dump her photos off for weeks at a time, so hers can fill up, but she doesn't look at them on her phone...it just happens. So she also wouldn't need much space.
