Once again Sony has created a great looking product that offers great audio quality, and then simply made it difficult for people to use. The 512MB Sony Network Walkman NW-E505 ($150 retail) should be an Editor's Choice-quality product. The sound quality is great, the battery lasts more than 50 hours, and it even comes in cute Pink and Blue metallic colors. Unfortunately, the set up is anything but simple. According to the PC Magazine review:

You have to set up a Sony Connect account and authorize the player before you can use it. Finally, you import your music into SonicStage and transfer it to the device. The SonicStage software is very annoying to use; it's clunky, slow, and a bit confusing.

I don't expect a lot from a flash-based player, but that seems like way to much hassle. Plus, it doesn't even support WMA files. As long as Sony keeps pushing SonyConnect over all other services, its MP3 players will be an also-ran in the market.
