Query: How can folks say this thing is easy to use?

I was so excited when I ordered this MP3 player. I got it and it was MUCH smaller than I imagined. The back light does not stay on 100% of the time- I have NO idea how people can see what they are doing. The sensitivity of the touch pad is absolutely insane. I have tried and tried to get this touch pad down but it is just SO sensitive that I can not get it to operate easily. I tried to adjust the back light and I could never get it to STAY and move to the section I needed. It kept jumping around and driving me crazy. It was like a mouse out of control. I do NOT like the the touch pad and after down loading the 65 page manual and attempting to read it- I decided to return this thing. Believe me- I am not a techno dinosour. I am a business professional who understands computers and high tech. I don't have a week to learn how to use this.
