Unknown Icons

Yesterday my friend's 13 years old daughter asked me a question I couldn't answer. "What is that icon on the 'Save' button?" she asked, "What does it mean?"

It took me a couple of moments to figure out what she's talking about. Then it took me several minutes to explain.

"Why would anyone use a 1.5 Mb ugly box, when you can save 4Gb on a tiny flash drive?"

Well, here it is. A whole new generation of users who never saw a 3½-inch diskette.

What should I draw on a save button, so "MySpace-generation" would understand? Is it time to rethink our usability standards? Or should we stick to the classics?
