If you're a parent with small children, you likely know that birthdays are a much bigger deal than they were when you were growing up. No more simple cake and pinata affairs; now it's inflatable jumpies, jugglers, puppet shows, goodie bags, and maybe even a pony or two. So the idea of a giant inflatable boombox may not be so crazy as it sounds (or looks).
Think about it: You and you neighbors can chip in for an "iBig Box" with its built-in MP3 player, speakers, dock, and fabric controls. Instant backyard party atmosphere, and you can pass it around from family to family as needed.
And if it gets damaged by screaming 8-year-olds, it won't be the biggest loss at $60. Then again, it may not survive the first party.
