Take my anecdotes with as big a grain of salt as you like, but analytically the benefits didn't outweigh the cons in my case. Not having access to the same video games, movies and entertainment as my peers greatly damaged my ability to form relationships at a young age. The only upside was perhaps a marginal increase in analytical thinking skills, which was easily offset by the anxiety/insecurities and resultant academic underperformance I had as a result of underdeveloped social skills. Your kids' mileage may vary.
Sure I grew up and that's all long in the past now, but that doesn't mean it was useful, justified, or harmless. When the fiancée and I decide to have kids, I intend to give them every opportunity I can within reason, that includes the resources for a vibrant social life if they want. Obviously I won't be buying them Grand Theft Auto at age 6, but Star Wars? Absolutely.
