Query: its really cool

i just got this as a christmas gift, and, regardless of what others have been saying, its a great player. its never skipped a beat, the sound quality is great, and its way more affordable than a RioVolt! it comes with an AC adapter, and its own music managment software. its great! the only bad part is the player is slightly heavy, and it takes four AA bateries.
