The Clip Sport is imo a disappointment. they should have just stuck with everything in the Clip Zip but added a larger capacity battery and a larger screen for the slightly larger form factor player.
I would love to see player the shape of the original Fuze but slightly thicker with 50+ hours of battery life, the same processor and circuitry as the Fuze, except for controls like on the Clip Zip, and a standard micro usb connector. Hopefully this would be priced at $99(or less?) for an 8GB version. It would be even better if it could have two card slots. Adding support for micro SDXC cards without having to format them as FAT32 would be great.
