Howdy, been lurking for a while and this is my first post. I have had an S50 from around 2005. I have 2 vehicles and a home dock and use it at the gym a couple days a week. The thing is solid and works well. I am having trouble with it regarding the battery. The charge indicator says 100% but no juice so I'm buying another battery. Other than that no problems ever. I really like the idea of recording a song while driving around. Not sure how long this S50 will last so... Is there a newer unit on the market that is like the S50 ? Thanks for any help.
