Okay, before I get into this.  I have to let everyone know that this is the first flip phone I've ever owned.  All of my previous phones were candybar style Nokias.  The KRZR is an excellent phone, still a little pricy, but beautiful to behold.  The MP3 player function is quite good.  The volume and clarity for such a small object are top notch.  Colors are bright and vibrant.  I think my favorite feature of all of them is the voice command function.  That in itself made it worthy of a five star rating.  I have only one complaint.  The menus can be quite complex and detail intensive at times.  The manual deffinitely came in handy a couple of times.  But otherwise this thing is worth its weight in gold.
