I personally see these mp4 players much like you wuzzupnshiat , but it really depends on how much you paid for yours as I wouldn't pay more then 60$

They are more of a curiosity then real MP3 players for daily use.
They work as your main mp3 player but at the same time it's also a much better idea to spend the extra 100$ and get a real player that has a decent battery life/ interface eg IPOD, Meizu, Zen, Clix

To hear that your model still doesn't support file browsing seems like you have the older gen nano clones.

The new ones should have a better interface but still a weak battery life.

Would I recommend a chipod to a friend, probably not unless they were on a super tight budget
