he has an interesting point, but its hard to say for sure that the mac mini will be the tipping point for apple.
i don't know if this was where the blogger was going, but read malcolm gladwell's "The Tipping Point" where he examines social phenomenon and what makes something go from obscure to popular seemingly overnight. While the mac mini might be what makes apple tip, i think only time will truly tell. i also don't think price point is the entire focal point for what will make apple tip (if it was, ipod would have tipped at ipod shuffle, not when big ipod ruled the show.
