Query: Breaks easily, bad interface, terrible warranty

My Sleek stopped working correctly after sustaining one fall from waist height. Now, sound only comes out of the right side speaker, which is infuriating, and leads to a product that brings more rage than joy. Furthermore, attempting to get anything done with the warranty requires jumping through a few hundred hoops, paying fees, and (oh yeah) you must keep your receipt. Forever. Also, this machine has a TERRIBLE computer program for loading songs onto it etc. It was an absolute exercise in frustration just to get them on there, only to have it break six months in after one fall from waist height. I thought I would be enlightened and get an iPod competitor for a lower price and with neat-looking features. My next MP3 will certainly be an iPod.
