Query: User friendly, easy to convert and transfer files

After reading previous reviews, I purchased the Sansa 4G player and find it very user friendly to convert files and upload MP3s directly from Windows Media player. I had no problems and get very good FM reception on the player. I had small video clips, photos and MP3s all loaded to the player within an hour of receipt. I am very pleased with the purchase.
