Query: Grossly Overpriced & Horrendously Engineered

While the iFP-190T is impressively compact, looks nice, and sounds reasonably decent, the controls and functionality were apparently designed by an incompetent madman with an evil sense of humor. The users manual is slightly more than worthless and the device itself is less intuitive than a box of cereal. Learning to navigate is a matter of painful trial & error. The Music Manager software that comes with the device is cumbersome and amazingly limited. Also, for reasons passing understanding, iRiver does not support MusicMatch downloads. In summary, the iFP-190T is an ill-conceived, poorly executed, absurdly expensive doorstop.
