Stretching Storage with Smart Playlists
"What, exactly, does your media tangibly become when you rip a CD or a DVD into a digital media file?"
There was a time when that was a meaningless question suitable only for philosophy professors and the insane, who dress better. Now we know beyond any doubt: It turns into a gaseous substance. That's why the iPhone and other media devices are so tightly sealed. It's not so much keeping the moisture out as it is trying to keep the Oingo Boingo in.
A gas expands to occupy the full dimensions of whatever container you put it in. And so it is for your iPhone. The capacity of an iPhone or iPod Touch can be 64, 32, 16, 8, or even 4 gigabytes if you bought it in the very first month of release and went cheap and never bothered to upgrade. But the number couldn't matter less. When you upgraded your 8-gig first-generation iPhone to a 32-gig iPhone 3G S, the extra space felt glorious and expansive ... until about a week later, when after seven days of adding just one more movie, podcast, or playlist you were reintroduced to the "Some Files Could Not Be Copied" error.
