i dont use rpm's. in my opinion, you loose alot of the benifits of compiling your own software. i actually run gentoo, and though the os itself was failry complicated to setup, it has a great software installation system. no hassles, and complete control.
anyway... i dont want to start an os war here. these things tend to get out of hand hehe. linux isn't for everyone, and IMO, you should use what you are comfortable with.
