I recently bought an IGO charger tip for my 650. It has no center wire like the original palmone & others I've seen. According to palmone support: "There is no need for you to worry for your charger that lacks the center rod on its prong. Basically, the purpose of that part is to prevent any possible ground that may cause unwanted behavior to any electronic devices."

That didn't sound very comforting. What do the experts here think? Should I insist on a charger with the center ground?
