Since our kids will never know what we used as our go-to portable technology for listening to music, you can give them a taste of how it was growing up in the 80's (without having to sit through a VH1 special) with the AirCassette ($2). Along with a nostalgic design, the AirCassette for your iPhone or iPod plays music while it animates the tape reels and displays the track info on the cassette label. For added bonus, you can create your own mixtapes and share them via email or on Facebook, as well as rewind or fast forward through songs without the need for a pencil.
