Edgar Bronfman Jr., who perfected the art of making a small fortune out of a big fortune, is playing the techno-visionary and predicting IPod is going to be pummeled by cellphone. Sure, the networks are here, they are almost free, and downloading music is a breeze wirelessly. Dude, just a word of advice: stick to being a playboy. That’s where daddy’s dollars are put to good use. Leave technology, and hits to people who know how to make them. And when you forget it all, well remember you are the guy who overpaid for Vivendi. A french water works company. And as a reality check: Seagrams’ baby!
